[PATCH] Fix apm suspend with cs4231 based sound cards

[Keith Duthie]

The following patch (effectively a reversion of a change between alsa
0.9.4 and 0.9.5) fixes a problem whereby an APM suspend causes the
program which is using the PCM device to enter the uninterruptible sleep
state on resume and thus causes the sound device to be unusable.

I've cc'ed alsa-user instead of alsa-devel as I'm only subscribed to
alsa-user, and my attempt to report this in February (according to an
automated reply I received) "Is being held until the list moderator can
review it for approval."
