Pull sound fixes from Takashi Iwai:
 "This contains the collection of small fixes for 4.11 that were pending
  during my vacation:

   - a few HD-audio quirks (more Dell headset support, docking station
     support on HP laptops)

   - a regression fix for the previous ctxfi DMA mask fix

   - a correction of the new CONFIG_SND_X86 menu entry

   - a fix for the races in ALSA sequencer core spotted by syzkaller"
