Merge tag 'sound-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "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"
