Arnd Bergmann 3915bf2946 ALSA: seq_timer: use monotonic times internally
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.

Amitoj Kaur Chawla d169133889 ALSA: ctxfi: Change structure initialisation to C99 style
For readability and to allow for structure randomisation, replace the
in order struct initialisation style with explicit field style.

struct i1 {

Arnd Bergmann cfecf1afd3 sound: oss: avoid time_t usage
We want to remove all time_t users from the kernel because of
y2038 compatibility. This particular instance does not even
use time_t to store a seconds value, so we can simply use
'unsigned int', which seems more fitting anywhere.

The same code is used in two OSS files.

Bhaktipriya Shridhar 43aa56d95d ALSA: sh: aica: Remove deprecated create_workqueue
System workqueues have been able to handle high level of concurrency
for a long time now and there's no reason to use dedicated workqueues
just to gain concurrency. Since aica_queue for AICA sound
driver has workitem dreamcastcard->spu_dma_work (maps to run_spu_dma)
which is involved in aica dma transfers and is not being used on a memory
reclaim path, dedicated aica_queue has been replaced with the
use of system_wq.

Unlike a dedicated per-cpu workqueue created with create_workqueue(),
system_wq allows multiple work items to overlap executions even on
the same CPU; however, a per-cpu workqueue doesn't have any CPU
locality or global ordering guarantees unless the target CPU is
explicitly specified and thus the increase of local concurrency
shouldn't make any difference.

Since the work items could be pending, flush_work() has been used in
snd_aicapcm_pcm_close() to ensure that there is no pending task while
disconnecting the driver.

Takashi Iwai fabc16fe9a ALSA: hda - Turn off loopback mixing as default
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.
