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"
