Pull sound fixes from Takashi Iwai:
 "Most of changes are small and easy cleanup or fixes:

   - a few HD-audio Realtek codec fixes and quirks
   - Intel HDMI audio fixes for Broadwell and Haswell / ValleyView
   - FireWire sound stack cleanups
   - a couple of sequencer core fixes
   - compress ABI fix for 64bit
   - conversion to modern ktime*() API"
