      ALSA: control: add dimension validator for userspace elements · 860c1994
      由 Takashi Sakamoto 提交于 
      The 'dimen' field in struct snd_ctl_elem_info is used to compose all of
members in the element as multi-dimensional matrix. The field has four
members. Each member represents the width in each dimension level by
element member unit. For example, if the members consist of typical
two dimensional matrix, the dimen[0] represents the number of rows
and dimen[1] represents the number of columns (or vise-versa).

The total members in the matrix should be exactly the same as the number
of members in the element, while current implementation has no validator
of this information. In a view of userspace applications, the information
must be valid so that it cannot cause any bugs such as buffer-over-run.

This commit adds a validator of dimension information for userspace
applications which add new element sets. When they add the element sets
with wrong dimension information, they receive -EINVAL.

      ALSA: ppc/awacs: shut up maybe-uninitialized warning · b268c34e
      由 Arnd Bergmann 提交于 
      The awacs sound driver produces a false-positive warning in ppc64_defconfig:

sound/ppc/awacs.c: In function 'snd_pmac_awacs_init':
include/sound/control.h:219:9: warning: 'master_vol' may be used uninitialized in this function [-Wmaybe-uninitialized]

I haven't come up with a good way to rewrite the code to avoid the
warning, so here is a bad one: I initialize the variable before
the conditionall initialization so gcc no longer has to worry about
it.

      ALSA: seq_timer: use monotonic times internally · 3915bf29
      由 Arnd Bergmann 提交于 
      The sequencer client manager reports timestamps in units of unsigned
32-bit seconds/nanoseconds, but that does not suffer from the y2038
overflow because it stores only the delta since the 'last_update'
time was recorded.

However, the use of the do_gettimeofday() function is problematic
and we have to replace it to avoid the overflow on on 32-bit
architectures.

This uses 'struct timespec64' to record 'last_update', and changes
the code to use monotonic timestamps that do not suffer from leap
seconds and settimeofday updates.

As a side-effect, the code can now use the timespec64_sub() helper
and become more readable and also avoid a multiplication to convert
from microseconds to nanoseconds.

      ALSA: hda - Turn off loopback mixing as default · fabc16fe
      由 Takashi Iwai 提交于 
      So far, we enabled the loopback mixing control as default, as this
behavior made somewhat compatible with the earlier HD-audio drivers
for Realtek & co.  However, it's getting annoying as we've got more
and more bug reports about the noise coming from the loopback route.
Since the loopback mixing is used fairly rarely and often harmful
(e.g. using PA), let's get rid of the default turn-on lines.
