ASoC: Intel: cht_bsw_max98090_ti: Fix jack initialization

2018-08-17T18:59:29+00:00

commit 3bbda5a38601f7675a214be2044e41d7749e6c7b upstream.

If the ts3a227e audio accessory detection hardware is present and its
driver probed, the jack needs to be created before enabling jack
detection in the ts3a227e driver. With this patch, the jack is
instantiated in the max98090 headset init function if the ts3a227e is
present. This fixes a null pointer dereference as the jack detection
enabling function in the ts3a driver was called before the jack is
created.

[minor correction to keep error handling on jack creation the same
as before by Pierre Bossart]

ALSA: hda/ca0132: fix build failure when a local macro is defined

2018-08-03T05:55:23+00:00

[ Upstream commit 8e142e9e628975b0dddd05cf1b095331dff6e2de ]

DECLARE_TLV_DB_SCALE (alias of SNDRV_CTL_TLVD_DECLARE_DB_SCALE) is used but
tlv.h is not included. This causes build failure when local macro is
defined by comment-out.

This commit fixes the bug. At the same time, the alias macro is replaced
with a destination macro added at a commit 46e860f76804 ("ALSA: rename
TLV-related macros so that they're friendly to user applications")

ALSA: usb-audio: Apply rate limit to warning messages in URB complete callback

2018-08-03T05:55:21+00:00

[ Upstream commit 377a879d9832f4ba69bd6a1fc996bb4181b1e504 ]

retire_capture_urb() may print warning messages when the given URB
doesn't align, and this may flood the system log easily.
Put the rate limit to the message for avoiding it.

ALSA: emu10k1: Rate-limit error messages about page errors

2018-08-03T05:55:20+00:00

[ Upstream commit 11d42c81036324697d367600bfc16f6dd37636fd ]

The error messages at sanity checks of memory pages tend to repeat too
many times once when it hits, and without the rate limit, it may flood
and become unreadable.  Replace such messages with the *_ratelimited()
variant.

ASoC: dpcm: fix BE dai not hw_free and shutdown

2018-08-03T05:55:16+00:00

[ Upstream commit 9c0ac70ad24d76b873c1551e27790c7f6a815d5c ]

In case, one BE is used by two FE1/FE2
FE1--->BE-->
       |
FE2----]
when FE1/FE2 call dpcm_be_dai_hw_free() together
the BE users will be 2 (> 1), hence cannot be hw_free
the be state will leave at, ex. SND_SOC_DPCM_STATE_STOP

later FE1/FE2 call dpcm_be_dai_shutdown(),
will be skip due to wrong state.
leaving the BE not being hw_free and shutdown.

The BE dai will be hw_free later when calling
dpcm_be_dai_shutdown() if still in invalid state.

ALSA: rawmidi: Change resized buffers atomically

2018-07-25T09:23:58+00:00

commit 39675f7a7c7e7702f7d5341f1e0d01db746543a0 upstream.

The SNDRV_RAWMIDI_IOCTL_PARAMS ioctl may resize the buffers and the
current code is racy.  For example, the sequencer client may write to
buffer while it being resized.

As a simple workaround, let's switch to the resized buffer inside the
stream runtime lock.

ALSA: hda - Handle pm failure during hotplug

2018-07-17T09:37:53+00:00

commit aaa23f86001bdb82d2f937c5c7bce0a1e11a6c5b upstream.

Obtaining the runtime pm wakeref can fail, especially in a hotplug
scenario where i915.ko has been unloaded. If we do not catch the
failure, we end up with an unbalanced pm.

v2 additions by tiwai:
hdmi_present_sense() checks the return value and handle only a
negative error case and bails out only if it's really still suspended.
Also, snd_hda_power_down() is called at the error path so that the
refcount is balanced.

Along with it, the spec->pcm_lock is taken outside
hdmi_present_sense() in the caller side, so that it won't cause
deadlock at reentrace via runtime resume.

v3 fix by tiwai:
Missing linux/pm_runtime.h is included.
