      ALSA: emu10k1: Fix deadlock in synth voice lookup · 95926035
      由 Takashi Iwai 提交于 
      The emu10k1 voice allocator takes voice_lock spinlock.  When there is
no empty stream available, it tries to release a voice used by synth,
and calls get_synth_voice.  The callback function,
snd_emu10k1_synth_get_voice(), however, also takes the voice_lock,
thus it deadlocks.

The fix is simply removing the voice_lock holds in
snd_emu10k1_synth_get_voice(), as this is always called in the
spinlock context.

      ALSA: hda - Replace strnicmp with strncasecmp · 8bb1ffdf
      由 Rasmus Villemoes 提交于 
      The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics
and a slightly buggy strncasecmp. The latter is the POSIX name, so
strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper
for the new strncasecmp to avoid breaking existing users.

To allow the compat wrapper strnicmp to be removed at some point in
the future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

      ALSA: hda - Use standard hda_jack infrastructure for CA0132 driver · f8fb1170
      由 Takashi Iwai 提交于 
      For its headphone, mic and DSP responses, we can use the standard
hda_jack infrastructure in CA0132 driver, too.  The only point to
handle carefully is the delayed headphone jack handling.  It tries to
react after a certain delay.  Here we use the existing block_report
flag in hda_jack_tbl (that was implemented for HDMI).

      ALSA: hda - Remove superfluous hooks from VIA driver · 7c3008c4
      由 Takashi Iwai 提交于 
      Like the previous fix for STAC/IDT codecs, the automute hooks in VIA
driver can be also removed by enabling the power control callback for
all pins.

      ALSA: hda - Remove superfluous callbacks from STAC/IDT codecs · aa699c49
      由 Takashi Iwai 提交于 
      Now we can register multiple callbacks to each jack, most of hooks
used in STAC/IDT codecs can be removed by enabling the powermap update
callback for all relevant pins.  Along with this, the call of
stac_init_power_map() can be moved back to stac_parse_auto_config()
and the own build_controls callback can be removed, too.

      ALSA: hda - Allow multiple callbacks for jack · 1a4f69d5
      由 Takashi Iwai 提交于 
      So far, hda_jack infrastructure allows only one callback per jack, and
this makes things slightly complicated when a driver wants to assign
multiple tasks to a jack, e.g. the standard auto-mute with a power
up/down sequence.  This can be simplified if the hda_jack accepts
multiple callbacks.

This patch is such an extension: the callback-specific part (the
function and private_data) is split to another struct from
hda_jack_tbl, and multiple such objects can be assigned to a single
hda_jack_tbl entry.

The new struct hda_jack_callback is passed to each callback function
now, thus the patch became bigger than expected.  But these changes
are mostly trivial.

      ALSA: lx6464es: Use nonatomic PCM ops · 6336c20c
      由 Takashi Iwai 提交于 
      Like the other previous changes, this patch for lx6464es takes the
same strategy for converting to nonatomic PCM ops: replacing spinlock
with mutex, converting the irq tasklet to the threaded irq, and
merging the trigger tasklets back to the trigger callback.

      This time PCXHR, another Digigram boards: like the previous patches,
the conversion is straightforward, replacing spinlocks with mutexes,
merging the irq tasklet into the threaded irq handler and the PCM
trigger tasklet back to the trigger callback.
