ALSA: hdspm - Constrain periods to 2 on older cards

2015-03-06T22:40:49+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()

2015-03-06T22:40:48+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

2015-02-11T06:48:17+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

2015-02-11T06:48:17+00:00

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.

ASoC: atmel_ssc_dai: fix start event for I2S mode

2015-02-11T06:48:17+00:00

commit a43bd7e125143b875caae6d4f9938855b440faaf upstream.

According to the I2S specification information as following:
  - WS = 0, channel 1 (left)
  - WS = 1, channel 2 (right)
So, the start event should be TF/RF falling edge.

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

2015-02-06T06:35:36+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.

ASoC: wm8960: Fix capture sample rate from 11250 to 11025

wm8960 codec can't support sample rate 11250, it must be 11025.

ALSA: hda - Fix wrong gpio_dir & gpio_mask hint setups for IDT/STAC codecs

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.

ALSA: hda - using uninitialized data

2015-01-16T14:59:01+00:00

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().
