[ALSA] alsa-kernel: schedule_timeout() fixes
Fix schedule_timeout() use in alsa-kernel. Mostly just schedule_timeout(1) --> schedule_timeout_uninterruptible(1) The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main, delete a superfluous set_current_state() and in soc/soc-dapm.c replace an _interruptible with _uninterruptible in some debug code; it's not waiting for signals.
