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

2015-01-26T12:53:13+00:00

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.

Merge branch 'for-linus' into for-next

2014-11-28T17:30:19+00:00

The commit [7a2e9ddc: ALSA: usb-audio: Add native DSD support for
Denon/Marantz DACs] requires the new format definition that has
landed only in for-next branch.

ALSA: core: Deletion of unnecessary checks before two function calls

2014-11-21T19:06:57+00:00

The functions snd_seq_oss_timer_delete() and vunmap() perform also input
parameter validation. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

ALSA: pcm: Fix document for snd_pcm_stop_xrun()

2014-11-10T06:38:22+00:00

Fix a copy & paste error:
 Warning(sound/core/pcm_native.c:1112): Excess function parameter 'state' description in 'snd_pcm_stop_xrun'

The state argument was dropped from snd_pcm_stop_xrun().

ALSA: pcm: Add snd_pcm_stop_xrun() helper

2014-11-09T17:20:40+00:00

Add a new helper function snd_pcm_stop_xrun() to the standard sequnce
lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the
existing open codes with this helper.

The function checks the PCM running state to prevent setting the wrong
state, too, for more safety.

ALSA: snd_ctl_activate_id(): Fix index look-up

2014-11-07T13:25:07+00:00

We want to know the offset for the id that was passed to the function, not
the offset of the first id of the control (which is always 0).

ALSA: pcm: Update the state properly before notification

2014-11-06T11:17:29+00:00

Some state changes (e.g. snd_pcm_stop()) sets the runtime state after
calling snd_timer_notify().  This is basically racy, since the
notification may wakes up the user even before the state change.
Although the possibility is low, we should set the state before the
notifications.

so that we can continue working on development of usb-audio stuff.

ALSA: pcm: Add xrun_injection proc entry

2014-11-04T13:09:16+00:00

This patch adds a new proc entry for PCM substreams to inject an
XRUN.  When a PCM substream is running and any value is written to its
xrun_injection proc file, the driver triggers XRUN.  This is a useful
feature for debugging XRUN and error handling code paths.

Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is
set.
