Merge tag 'sound-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "No surprises in this development cycle, and most of work is about the
  fixes and the improvements of the existing code, while a new LED
  control layer and a few new drivers have been introduced.

  Here are some highlights:

  Core:
   - A common mute-LED framework was introduced. It is used by HD-audio
     for now, more adaption will follow later. The former "Mic Mute-LED
     Mode" mixer control has been replaced with the corresponding sysfs
     now.
   - User-control management was changed to count consumed bytes instead
     of capping by number of elements; this will allow more controls in
     the normal usage pattern while avoiding the possible memory
     exhaustion DoS

  ASoC:
   - Continued refactoring and cleanups in ASoC core and generic card
     drivers
   - Wide range of small cppcheck and warning fixes
   - New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
     accessory detection, and Realtek RT1019, RT1316, RT711 and RT715

  USB-audio:
   - Continued improvements and fixes of the implicit feedback mode,
     including better support for Pioneer and Roland/BOSS devices

  HD-audio:
   - Default back to non-buffer preallocation on x86
   - Cirrus codec improvements, more quirks for Realtek codecs

  Others:
   - New virtio sound driver
   - FireWire Bebob updates"
