Joe Perches 6a73cf46ce sound: Use octal not symbolic permissions
Convert the S_<FOO> symbolic permissions to their octal equivalents as
using octal and not symbolic permissions is preferred by many as more
readable.

see: https://lkml.org/lkml/2016/8/2/1945

Done with automated conversion via:
$ ./scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace <files...>

o Wrapped one multi-line call to a single line

Kees Cook 7211ec6392 ALSA: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list
pointer to all timer callbacks, switch to using the new timer_setup()
and from_timer() to pass the timer pointer explicitly. These are all the
"mechanical" changes remaining in the sound subsystem.

Julia Lawall 5305239312 ALSA: constify ct_timer_ops structures
The ct_timer_ops structures are never modified, so declare them as const.

Done with the help of Coccinelle.

Rusty Russell a67ff6a540 ALSA: module_param: make bool parameters really bool
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Takashi Iwai 8dca419721 ALSA: ctxfi - Fix deadlock with xfi-timer
The PCM x-fi native update routine can cause deadlocks when the
trigger(START) is called while the stream is running.

This patch fixes the deadlock by just postponing the pcm period update
to the next possible wake-up.  Also it adds the flip of ti->running
flag (just to be sure as now).

Takashi Iwai 04145f2bfb ALSA: ctxfi - Add use_system_timer module option
Added use_system_timer module option to force to use the system timer
instead of emu20k1 timer irq for debugging.

Takashi Iwai 54de6bc8b2 ALSA: ctxfi - Optimize the native timer handling using wc counter
Optimize the timer update routine to look up wall clock once instead of
checking the position of each stream at each timer update.

Takashi Iwai b7bbf87608 ALSA: ctxfi - Use native timer interrupt on emu20k1
emu20k1 has a native timer interrupt based on the audio clock, which
is more accurate than the system timer (from the synchronization POV).
This patch adds the code to handle this with multiple streams.

The system timer is still used on emu20k2, and can be used also for
emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.
