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" * tag 'sound-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (35 commits) ALSA: dice: fix error path to destroy initialized stream data ALSA: hda - Skip jack and others for non-existing PCM streams ALSA: hda/realtek - change the location for one of two front mics ALSA: rme9652: Hardening for potential Spectre v1 ALSA: hdspm: Hardening for potential Spectre v1 ALSA: asihpi: Hardening for potential Spectre v1 ALSA: opl3: Hardening for potential Spectre v1 ALSA: hda: Hardening for potential Spectre v1 ALSA: control: Hardening for potential Spectre v1 ALSA: seq: oss: Hardening for potential Spectre v1 ALSA: seq: oss: Fix unbalanced use lock for synth MIDI device ALSA: hda/realtek - Update ALC255 depop optimize ALSA: hda/realtek - Add some fixes for ALC233 ALSA: pcm: Change return type to vm_fault_t ALSA: usx2y: Change return type to vm_fault_t ALSA: usb-audio: ADC3: Fix channel mapping conversion for ADC3.
