ALSA: usb-audio: fix Roland A-PRO support

2013-02-28T14:32:25+00:00

commit 7da58046482fceb17c4a0d4afefd9507ec56de7f upstream.

The quirk for the Roland/Cakewalk A-PRO keyboards accidentally used the
wrong interface number, which prevented the driver from attaching to the
device.

ALSA: rme32.c irq enabling after spin_lock_irq

2013-02-28T14:32:23+00:00

commit f49a59c4471d81a233e09dda45187cc44fda009d upstream.

According to the other code in this driver and similar
code in rme96 it seems, that spin_lock_irq in
snd_rme32_capture_close function should be paired
with spin_unlock_irq.

ALSA: ali5451: remove irq enabling in pointer callback

2013-02-28T14:32:23+00:00

commit dacae5a19b4cbe1b5e3a86de23ea74cbe9ec9652 upstream.

snd_ali_pointer function is called with local
interrupts disabled. However it seems very strange to
reenable them in such way.

ALSA: usb-audio: fix invalid length check for RME and other UAC 2 devices

2013-02-04T00:21:37+00:00

commit d56268fb108c7c21e19933588ca4d94652585183 upstream.

Commit 23caaf19b11e (ALSA: usb-mixer: Add support for Audio Class v2.0)
forgot to adjust the length check for UAC 2.0 feature unit descriptors.
This would make the code abort on encountering a feature unit without
per-channel controls, and thus prevented the driver to work with any
device having such a unit, such as the RME Babyface or Fireface UCX.

ALSA: pxa27x: fix ac97 cold reset

2013-01-17T16:44:08+00:00

commit 41b645c8624df6ace020a8863ad1449d69140f7d upstream.

Cold reset on the pxa27x currently fails and

     pxa2xx_ac97_try_cold_reset: cold reset timeout (GSR=0x44)

appears in the kernel log.  Through trial-and-error (the pxa270 developer's
manual is mostly incoherent on the topic of ac97 reset), I got cold reset to
complete by setting the WARM_RST bit in the GCR register (and later noticed that
pxa3xx does this for cold reset as well).  Also, a timeout loop is needed to
wait for the reset to complete.

Tested on a palm treo 680 machine.

ALSA: usb-audio: Fix missing autopm for MIDI input

2013-01-11T17:03:37+00:00

commit f5f165418cabf2218eb466c0e94693b8b1aee88b upstream.

The commit [88a8516a: ALSA: usbaudio: implement USB autosuspend] added
the support of autopm for USB MIDI output, but it didn't take the MIDI
input into account.

This patch adds the following for fixing the autopm:
- Manage the URB start at the first MIDI input stream open, instead of
  the time of instance creation
- Move autopm code to the common substream_open()
- Make snd_usbmidi_input_start/_stop() more robust and add the running
  state check

ALSA: usb-audio: Avoid autopm calls after disconnection

2013-01-11T17:03:36+00:00

commit 59866da9e4ae54819e3c4e0a8f426bdb0c2ef993 upstream.

Add a similar protection against the disconnection race and the
invalid use of usb instance after disconnection, as well as we've done
for the USB audio PCM.

ALSA: hda - Add support for Realtek ALC292

2012-12-03T20:59:15+00:00

commit af02dde8a609d8d071c4b31a82df811a55690a4a upstream.

We found a new codec ID 292, and that just a simple quirk would enable
sound output/input on this ALC292 chip.
