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"
