commit c507de88f6a336bd7296c9ec0073b2d4af8b4f5e upstream.
stac_store_hints() does utterly wrong for masking the values for
gpio_dir and gpio_data, likely due to copy&paste errors. Fortunately,
this feature is used very rarely, so the impact must be really small.

commit 69eba10e606a80665f8573221fec589430d9d1cb upstream.
In olden times the snd_hda_param_read() function always set "*start_id"
but in 2007 we introduced a new return and it causes uninitialized data
bugs in a couple of the callers: print_codec_info() and
hdmi_parse_codec().

commit d70a1b9893f820fdbcdffac408c909c50f2e6b43 upstream.
The Arcam rPAC seems to have the same problem - whenever anything
(alsamixer, udevd, 3.9+ kernel from 60af3d037eb8c, ..) attempts to
access mixer / control interface of the card, the firmware "locks up"
the entire device, resulting in
SNDRV_PCM_IOCTL_HW_PARAMS failed (-5): Input/output error
from alsa-lib.
Other operating systems can somehow read the mixer (there seems to be
playback volume/mute), but any manipulation is ignored by the device
(which has hardware volume controls).

commit 48826ee590da03e9882922edf96d8d27bdfe9552 upstream.
Commit 5fe5b767dc6f ("ASoC: dapm: Do not pretend to support controls for non
mixer/mux widgets") revealed ill-defined control in a route between
"STENL Mux" and DACs in max98090.c:
max98090 i2c-193C9890:00: Control not supported for path STENL Mux -> [NULL] -> DACL
max98090 i2c-193C9890:00: ASoC: no dapm match for STENL Mux --> NULL --> DACL
max98090 i2c-193C9890:00: ASoC: Failed to add route STENL Mux -> NULL -> DACL
max98090 i2c-193C9890:00: Control not supported for path STENL Mux -> [NULL] -> DACR
max98090 i2c-193C9890:00: ASoC: no dapm match for STENL Mux --> NULL --> DACR
max98090 i2c-193C9890:00: ASoC: Failed to add route STENL Mux -> NULL -> DACR
Since there is no control between "STENL Mux" and DACs the control name must
be NULL not "NULL".

commit 6e84a8d7ac3ba246ef44e313e92bc16a1da1b04a upstream.
This patch adds a USB control message delay quirk for a few specific Marantz/Denon
devices. Without the delay the DACs will not work properly and produces the
following type of messages:
Nov 15 10:09:21 orwell kernel: [ 91.342880] usb 3-13: clock source 41 is not valid, cannot use
Nov 15 10:09:21 orwell kernel: [ 91.343775] usb 3-13: clock source 41 is not valid, cannot use
There are likely other Marantz/Denon devices using the same USB module which exhibit the
same problems. But as this cannot be verified I limited the patch to the devices
I could test.
The following two devices are covered by this path:
- Marantz SA-14S1
- Marantz HD-DAC1

commit c251ea7bd7a04f1f2575467e0de76e803cf59149 upstream.
On a mx28evk with a sgtl5000 codec we notice a loud 'click' sound to happen
5 seconds after the end of a playback.
The SMALL_POP bit should fix this, but its definition is incorrect:
according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not
bit 1.
Fix the definition accordingly and enable the bit as intended per the code
comment.
After applying this change, no loud 'click' sound is heard after playback

commit 317168d0c766defd14b3d0e9c2c4a9a258b803ee upstream.
In compat mode, we copy each field of snd_pcm_status struct but don't
touch the reserved fields, and this leaves uninitialized values
there. Meanwhile the native ioctl does zero-clear the whole
structure, so we should follow the same rule in compat mode, too.

Adding support for Steinberg UR22 USB interface via quirks table patch
See Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1317244
Also see threads:
http://linux-audio.4202.n7.nabble.com/Support-for-Steinberg-UR22-Yamaha-USB-chipset-0499-1509-tc82888.html#a82917
http://www.steinberg.net/forums/viewtopic.php?t=62290
Tested by at least 4 people judging by the threads.
Did not test MIDI interface, but audio output and capture both are
functional. Built 3.17 kernel with this driver on Ubuntu 14.04 & tested with mpg123
Patch applied to 3.13 Ubuntu kernel works well enough for daily use.

commit 95926035b187cc9fee6fb61385b7da9c28123f74 upstream.
The emu10k1 voice allocator takes voice_lock spinlock. When there is
no empty stream available, it tries to release a voice used by synth,
and calls get_synth_voice. The callback function,
snd_emu10k1_synth_get_voice(), however, also takes the voice_lock,
thus it deadlocks.
The fix is simply removing the voice_lock holds in
snd_emu10k1_synth_get_voice(), as this is always called in the
spinlock context.

commit a9960e6a293e6fc3ed414643bb4e4106272e4d0a upstream.
The calculated frame size was wrong because snd_pcm_format_physical_width()
actually returns the number of bits, not bytes.
Use snd_pcm_format_size() instead, which not only returns bytes, but also

commit 7a9744cb455e6faa287e148394b4b422a6f3c5c4 upstream.
When a driver is set up without the jack detection explicitly (either
by passing a model option or via a specific fixup), the pin powermap
of IDT/STAC codecs is set up wrongly, resulting in the silence
output. It's because of a logic failure in stac_init_power_map().
It tries to avoid creating a callback for the pins that have other
auto-hp and auto-mic callbacks, but the check is done in a wrong way
at a wrong time. The stac_init_power_map() should be called after
creating other jack detection ctls, and the jack callback should be
created only for jack-detectable widgets.
This patch fixes the check in stac_init_power_map() and its callee
at the right place, after snd_hda_gen_build_controls().

commit f3ee07d8b6e061bf34a7167c3f564e8da4360a99 upstream.
ALC269 & co have many vendor-specific setups with COEF verbs.
However, some verbs seem specific to some codec versions and they
result in the codec stalling. Typically, such a case can be avoided
by checking the return value from reading a COEF. If the return value
is -1, it implies that the COEF is invalid, thus it shouldn't be
written.
This patch adds the invalid COEF checks in appropriate places
accessing ALC269 and its variants. The patch actually fixes the
resume problem on Acer AO725 laptop.

commit e24aa0a4c5ac92a171d9dd74a8d3dbf652990d36 upstream.
CA0132 driver tries to reload the firmware at resume. Usually this
works since the firmware loader core caches the firmware contents by
itself. However, if the driver failed to load the firmwares
(e.g. missing files), reloading the firmware at resume goes through
the actual file loading code path, and triggers a kernel WARNING like:
WARNING: CPU: 10 PID:11371 at drivers/base/firmware_class.c:1105 _request_firmware+0x9ab/0x9d0()
For avoiding this situation, this patch makes CA0132 skipping the f/w
loading at resume when it failed at probe time.

commit 883a1d49f0d77d30012f114b2e19fc141beb3e8e upstream.
The ALSA control code expects that the range of assigned indices to a control is
continuous and does not overflow. Currently there are no checks to enforce this.
If a control with a overflowing index range is created that control becomes
effectively inaccessible and unremovable since snd_ctl_find_id() will not be
able to find it. This patch adds a check that makes sure that controls with a
overflowing index range can not be created.

commit ac902c112d90a89e59916f751c2745f4dbdbb4bd upstream.
Each control gets automatically assigned its numids when the control is created.
The allocation is done by incrementing the numid by the amount of allocated
numids per allocation. This means that excessive creation and destruction of
controls (e.g. via SNDRV_CTL_IOCTL_ELEM_ADD/REMOVE) can cause the id to
eventually overflow. Currently when this happens for the control that caused the
overflow kctl->id.numid + kctl->count will also over flow causing it to be
smaller than kctl->id.numid. Most of the code assumes that this is something
that can not happen, so we need to make sure that it won't happen

commit fd9f26e4eca5d08a27d12c0933fceef76ed9663d upstream.
A control that is visible on the card->controls list can be freed at any time.
This means we must not access any of its memory while not holding the
controls_rw_lock. Otherwise we risk a use after free access.

commit 82262a46627bebb0febcc26664746c25cef08563 upstream.
There are two issues with the current implementation for replacing user
controls. The first is that the code does not check if the control is actually a
user control and neither does it check if the control is owned by the process
that tries to remove it. That allows userspace applications to remove arbitrary
controls, which can cause a user after free if a for example a driver does not
expect a control to be removed from under its feed.
The second issue is that on one hand when a control is replaced the
user_ctl_count limit is not checked and on the other hand the user_ctl_count is
increased (even though the number of user controls does not change). This allows
userspace, once the user_ctl_count limit as been reached, to repeatedly replace
a control until user_ctl_count overflows. Once that happens new controls can be
added effectively bypassing the user_ctl_count limit.
Both issues can be fixed by instead of open-coding the removal of the control
that is to be replaced to use snd_ctl_remove_user_ctl(). This function does
proper permission checks as well as decrements user_ctl_count after the control
has been removed.
Note that by using snd_ctl_remove_user_ctl() the check which returns -EBUSY at
beginning of the function if the control already exists is removed. This is not
a problem though since the check is quite useless, because the lock that is
protecting the control list is released between the check and before adding the
new control to the list, which means that it is possible that a different
control with the same settings is added to the list after the check. Luckily
there is another check that is done while holding the lock in snd_ctl_add(), so
we'll rely on that to make sure that the same control is not added twice.

commit 07f4d9d74a04aa7c72c5dae0ef97565f28f17b92 upstream.
The user-control put and get handlers as well as the tlv do not protect against
concurrent access from multiple threads. Since the state of the control is not
updated atomically it is possible that either two write operations or a write
and a read operation race against each other. Both can lead to arbitrary memory
disclosure. This patch introduces a new lock that protects user-controls from
concurrent access. Since applications typically access controls sequentially
than in parallel a single lock per card should be fine.

According to the bug reporter (Данило Шеган), the external mic
starts to work and has proper jack detection if only pin 0x19
is marked properly as an external headset mic.

Reset needs to wait 20ms before other codec IO is performed. This wait

The conversion to a fixup table for Replacer model with ALC260 in
commit 20f7d928 took the wrong widget NID for COEF setups. Namely,
NID 0x1a should have been used instead of NID 0x20, which is the
common node for all Realtek codecs but ALC260.

[note: the removal of ALC260_FIXUP_HP_PIN_0F chain is also needed as a
part of the fix; otherwise the pin is set up wrongly as a headphone,
and user-space (PulseAudio) may be wrongly trying to detect the jack

commit 44330ab516c15dda8a1e660eeaf0003f84e43e3f upstream.
The register CLASS_D_CONTROL_1 is marked as volatile because it contains
a bit, DAC_MUTE, which is also mirrored in the ADC_DAC_CONTROL_1
register. This causes problems for the "Speaker Switch" control, which
will report an error if the CODEC is suspended because it relies on a
volatile register.
To resolve this issue mark CLASS_D_CONTROL_1 as non-volatile and
manually keep the register cache in sync by updating both bits when
changing the mute status.

Intel chipsets for snooping, etc. Especially without snooping, the
audio playback stutters or gets corrupted. This fix patch just adds

commit 415d555e6b398b00fc1733f0113065a54df9106a upstream.
The recent fixups for HP laptops to support the mute LED made the
speaker output silent on some machines. It turned out that they use
the NID 0x18 for the speaker while it's also used for controlling the
LED via VREF bits although the current driver code blindly assumes
that such a node is a mic pin (where 0x18 is usually so).
This patch fixes the problem by only changing the VREF bits and
keeping the other pin ctl bits.
