    sys/dev/sound/pcm    dsp.c mixer.c 
  Log:
  Fix sound LOR problems:
  
  dsp_open: rearrange to only hold one lock at a time
  
  dsp_close: ditto
  
  mixer_hwvol_init: delete locking, the only consumer seems to
  be the ess driver and it only call it a creation time, I
  think the device will be stable across the sleepable malloc.
  
  cmi interrupt routine: Release locks while caller chn_intr,
  either this or do what emu10k1 does which is have no locks
  at in the interrupt handler.
