ASoC: omap-pcm: Correct dma mask

2015-03-18T12:31:34+00:00

commit d51199a83a2cf82a291d19ee852c44caa511427d upstream.

DMA_BIT_MASK of 64 is not valid dma address mask for OMAPs, it should be
set to 32.
The 64 was introduced by commit (in 2009):
a152ff24b978 ASoC: OMAP: Make DMA 64 aligned

But the dma_mask and coherent_dma_mask can not be used to specify alignment.

ALSA: hda - Disable runtime PM for Panther Point again

2015-03-18T12:31:31+00:00

commit de5d0ad506cb10ab143e2ffb9def7607e3671f83 upstream.

This is essentially a partial revert of the commit [b1920c21102a:
'ALSA: hda - Enable runtime PM on Panther Point'].  There was a bug
report showing the HD-audio bus hang during runtime PM on HP Spectre
XT.

ALSA: hda - Add pin configs for ASUS mobo with IDT 92HD73XX codec

2015-03-18T12:31:31+00:00

commit 6426460e5d87810e042962281fe3c1e8fc256162 upstream.

BIOS doesn't seem to set up pins for 5.1 and the SPDIF out, so we need
to give explicitly here.

ALSA: pcm: Don't leave PREPARED state after draining

2015-03-18T12:31:31+00:00

commit 70372a7566b5e552dbe48abdac08c275081d8558 upstream.

When a PCM draining is performed to an empty stream that has been
already in PREPARED state, the current code just ignores and leaves as
it is, although the drain is supposed to set all such streams to SETUP
state.  This patch covers that overlooked case.

ALSA: hdspm - Constrain periods to 2 on older cards

2015-03-06T22:43:24+00:00

commit f0153c3d948c1764f6c920a0675d86fc1d75813e upstream.

RME RayDAT and AIO use a fixed buffer size of 16384 samples. With period
sizes of 32-4096, this translates to 4-512 periods.

The older RME cards have a variable buffer size but require exactly two
periods.

This patch enforces nperiods=2 on those cards.

ALSA: off by one bug in snd_riptide_joystick_probe()

2015-03-06T22:43:24+00:00

commit e4940626defdf6c92da1052ad3f12741c1a28c90 upstream.

The problem here is that we check:

	if (dev >= SNDRV_CARDS)

Then we increment "dev".

       if (!joystick_port[dev++])

Then we use it as an offset into a array with SNDRV_CARDS elements.

	if (!request_region(joystick_port[dev], 8, "Riptide gameport")) {

This has 3 effects:
1) If you use the module option to specify the joystick port then it has
   to be shifted one space over.
2) The wrong error message will be printed on failure if you have over
   32 cards.
3) Static checkers will correctly complain that are off by one.

ALSA: ak411x: Fix stall in work callback

2015-02-11T06:54:49+00:00

commit 4161b4505f1690358ac0a9ee59845a7887336b21 upstream.

When ak4114 work calls its callback and the callback invokes
ak4114_reinit(), it stalls due to flush_delayed_work().  For avoiding
this, control the reentrance by introducing a refcount.  Also
flush_delayed_work() is replaced with cancel_delayed_work_sync().

The exactly same bug is present in ak4113.c and fixed as well.

ASoC: sgtl5000: add delay before first I2C access

commit 58cc9c9a175885bbf6bae3acf18233d0a8229a84 upstream.

To quote from section 1.3.1 of the data sheet:
	The SGTL5000 has an internal reset that is deasserted
	8 SYS_MCLK cycles after all power rails have been brought
	up. After this time, communication can start

	...
	1.0us represents 8 SYS_MCLK cycles at the minimum 8.0 MHz SYS_MCLK.

According to the I2S specification information as following:

  - WS = 1, channel 2 (right)
So, the start event should be TF/RF falling edge.

ALSA: seq-dummy: remove deadlock-causing events on close

2015-02-06T06:35:49+00:00

commit 0767e95bb96d7fdddcd590fb809e6975d93aebc5 upstream.

When the last subscriber to a "Through" port has been removed, the
subscribed destination ports might still be active, so it would be
wrong to send "all sounds off" and "reset controller" events to them.
The proper place for such a shutdown would be the closing of the actual
MIDI port (and close_substream() in rawmidi.c already can do this).

This also fixes a deadlock when dummy_unuse() tries to send events to
its own port that is already locked because it is being freed.
