ALSA: control: Add sanity checks for user ctl id name string

2015-03-12T06:36:38+00:00

There was no check about the id string of user control elements, so we
accepted even a control element with an empty string, which is
obviously bogus.  This patch adds more sanity checks of id strings.

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

2015-02-23T15:48:18+00:00

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: seq: potential out of bounds in do_control()

2015-02-12T10:07:48+00:00

Smatch complains that "control" is user specifigy and needs to be
capped.  The call tree to understand this warning is quite long.

ALSA: control: fix failure to return new numerical ID in 'replace' event data

2015-02-09T15:23:25+00:00

In 'replace' event data, numerical ID of control is always invalid. This
commit fix this bug so as the event data has renewed numerical ID for
control.

ALSA: pcm: allow for trigger_tstamp snapshot in .trigger

2015-02-09T15:01:53+00:00

Don't use generic snapshot of trigger_tstamp if low-level driver or
hardware can get a more precise value for better audio/system time
synchronization.

ALSA: pcm: don't override timestamp unconditionally

2015-02-09T15:01:21+00:00

timestamp in RUNNING mode is already taken in update_hw_ptr routine,
getting a new timestamp introduces offset between hw_ptr, audio_tstamp
and system time

Add else condition to read timestamp as fallback and only when
enabled

ALSA: control: fix failure to return numerical ID in 'add' event

2015-02-08T14:31:09+00:00

Currently when adding a new control, the assigned numerical ID is not
set for event data, thus userspace applications cannot realize it just
by event data.

ALSA: Add a helper to add a new attribute group to card

2015-02-06T08:56:33+00:00

For assigning sysfs entries for a card device from the driver,
introduce a new helper function, snd_card_add_dev_attr().  In this
way, we can avoid the possible race between the device registration
and the sysfs addition / removal.

The driver can pass a new attribute group to add freely.  This has to
be called before snd_card_register().

Currently, up to two extra groups can be added.  More than that, it'll
return an error.
