sound fixes for 4.17-rc3 

A significant amount of fixes have been piled up at this time.
 
 - Possible Spectre v1 coverage in OSS sequencer API, control API,
   HD-audio hwdep ioctl, ASIHPI hwdep ioctl, OPL3, and HDSPM/RME
   channel_info API.
 
 - A regression fix in PCM delay reporting that happened at the code
   refactoring for the set_fs() removal
 
 - The long-standing bug in PCM sync_ptr ioctl that missed the audio
   timestamp field
 
 - USB-audio regression fixes due to the recent UAC2 jack support
 
 - vm_fault_t conversions in a couple of places
 
 - ASoC topology API fixes
 
 - Assorted driver fixes:
   * ASoC rsnd, FSL, Intel SST, DMIC, AMD, ADAU17x1, Realtek codec
   * FireWire typo fix
   * HD-audio quirks and USB-audio Dell fixup
   * USB-audio UAC3 corrections
