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"
