ALSA: usb-audio: Use Class Specific EP for UAC3 devices.

2018-05-15T05:29:10+00:00

bmAtributes offset doesn't exist in the UAC3 CS_EP descriptor.
Hence, checking for pitch control as if it was UAC2 doesn't make
any sense. Use the defined UAC3 offsets instead.

ALSA: usb: mixer: volume quirk for CM102-A+/102S+

2018-05-13T16:53:53+00:00

Currently it's not possible to set volume lower than 26% (it just mutes).

Also fixes this warning:

  Warning! Unlikely big volume range (=9472), cval->res is probably wrong.
  [13] FU [PCM Playback Volume] ch = 2, val = -9473/-1/1

, and volume works fine for full range.

ALSA: usx2y: Change return type to vm_fault_t

2018-04-25T06:15:20+00:00

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

The channel mapping is defined by bChRelationship, not bChPurpose.

ALSA: usb-audio: Skip broken EU on Dell dock USB-audio

2018-04-24T11:39:30+00:00

The Dell Dock USB-audio device with 0bda:4014 is behaving notoriously
bad, and we have already applied some workaround to avoid the firmware
hiccup.  Yet we still need to skip one thing, the Extension Unit at ID
4, which doesn't react correctly to the mixer ctl access.

ALSA: usb-audio: Fix missing endian conversion

2018-04-24T11:36:28+00:00

The UAC2 jack detection support introduced the bmControls checks in a
couple of places, but they forgot the endian conversion; the
bmControls of UAC2 terminal descriptor is __le16, not a byte like in
UAC1.

ALSA: usb-audio: Fix forgotten conversion of control query functions

2018-04-23T14:20:29+00:00

The recent code refactoring made the argument for some helper
functions to be the explicit UAC_CS_* and UAC2_CS_* value instead of
0-based offset.  However, there was one place left forgotten, and it
caused a regression on some devices appearing as the inconsistent
mixer setup.

This patch corrects the forgotten conversion.

ALSA: line6: Use correct endpoint type for midi output

2018-04-12T06:42:07+00:00

Sending MIDI messages to a PODxt through the USB connection shows
"usb_submit_urb failed" in dmesg and the message is not received by
the POD.

The error is caused because in the funcion send_midi_async() in midi.c
there is a call to usb_sndbulkpipe() for endpoint 3 OUT, but the PODxt
USB descriptor shows that this endpoint it's an interrupt endpoint.

Patch tested with PODxt only.

[ The bug has been present from the very beginning in the staging
  driver time, but Fixes below points to the commit moving to sound/
  directory so that the fix can be cleanly applied -- tiwai ]

ALSA: usb-audio: Add sanity checks in UAC3 clock parsers

2018-04-07T11:07:17+00:00

The UAC3 clock parser codes lack of the sanity checks for malformed
descriptors like UAC2 parser does.  Without it, the driver may lead to
a potential crash.

ALSA: usb-audio: More strict sanity checks for clock parsers

2018-04-07T11:07:11+00:00

The sanity checks introduced for malformed descriptors loosely check
the given descriptor size, although the size greater than the defined
description is invalid.  It was due to a concern of any funky firmware
in the actual products.  But this doesn't look hitting, and any sane
products must have the defined descriptors.

So in this patch, we make the validators more strict, allowing only
with the defined descriptor sizes.  The value in clock selector
validator is corrected from 5 to 7 to count the two unlisted fields
after baCSourceID[].
