Merge tag 'sound-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"It's been a fairly calm development cycle. There are a few last-minute
ALSA core fixes, most notably for covering PCM ioctl races, but the
most of rest are device-specific changes.
Below are some highlights:
ALSA core:
- Fixes for PCM ioctl races that may lead to UAF
- Fix for oversized allocations in PCM OSS layer
ASoC:
- Start of moving SoF to support multiple IPC mechanisms
- Use of NHLT ACPI table to reduce the amount of quirking required
for Intel systems
- Preliminary works forthcoming Intel AVS driver for legacy Intel DSP
firmwares
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280,
Renesas RZ/V2L, Texas Instruments TAS585M
HD-audio:
- Driver re-binding fix for HD-audio
- Updates for Intel ADL and Tegra234, various platform quirks for
Dell, HP, Lenovo, ASUS, Samsung and Clevo machines
USB-audio:
- Quirk updates for Scarlett2, RODE, Corsair devices"
