This patch is concerned with migrating the time variables in the pcxhr
module found in the sound driver. The changes are concerend with the
y2038 problem where timeval will overflow in the year 2038. ktime_t
was used instead of timeval to get the wall time. The difference
is displayed now in nanoseconds instead of microseconds.

request_module() handles the printf style arguments, so we don't have
to render strings in the caller side.  Not only it reduces the
unnecessary temporary string buffer, it's even safer from the security
POV.

snd_bebob_stream_check_internal_clock() may get an id from
saffirepro_both_clk_src_get (via clk_src->get()) that was uninitialized.

a) make logic in saffirepro_both_clk_src_get explicit
b) test if id used in snd_bebob_stream_check_internal_clock matches array size

Terratec PHASE 88 rack fw has two registers for source of clock, one is
for internal/external, and another is for wordclock/spdif for external.

When clock source is internal, information in another register has no meaning.
Thus it must be ignored, but current implementation decodes it. This causes
over-indexing reference to labels.

On x86, using dma_mmap_coherent() for the pages allocated via
dma_alloc_coherent() results in a warning like:
  aplay:32536 map pfn RAM range req uncached-minus for [mem 0x21d500000-0x21d51ffff], got write-back

Until the issue is addressed in the core side, take back to the old
good way in PCM code only for x86.

Without this terminating entry, the pin matching would continue
across random memory until a zero or a non-matching entry was found.

The result being that in some cases, the pin quirk would not be
applied correctly.

Use strncpy() instead of strcpy(). That's not a security issue, as the

Some architectures like PARISC is known not to support mmap properly
with the DMA buffer, where dma_mmap_coherent() returns -EINVAL
unconditionally.  From the API POV, we should rather drop the mmap
support there and expose it before the user-space tries to call mmap.

The patch contains again ugly ifdef's, unfortunately, as there is no
global flag indicating this.  Once when such macro is defined, we can
get rid of this instead.

As PCM core handles the multiple linked streams in parallel, lockdep
gets confused (partly because of weak annotations) and spews the
false-positive warnings.  This hasn't been a problem for long time but
the latest PCM lock path update seems to have woken up a sleeping
dog.

Here is an attempt to paper over this issue: pass the lock subclass
just calculated from the depth in snd_pcm_action_group().  Also, a
(possibly) wrong lock subclass set in snd_pcm_action_lock_mutex() is
dropped, too.

As of now the pointer to struct dai is not being used anywhere in the
function. So it is safe to remove the variable.
If we are ever doing anything with the container_of(daio, struct dai, daio),
then at that time we can again add the variable.
