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" * tag 'sound-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (587 commits) ALSA: hda/conexant: Re-order CX5066 quirk table entries ALSA: hda/realtek: Remove redundant entry for ALC861 Haier/Uniwill devices ALSA: hda/realtek: Re-order ALC662 quirk table entries ALSA: hda/realtek: Re-order remaining ALC269 quirk table entries ALSA: hda/realtek: Re-order ALC269 Lenovo quirk table entries ALSA: hda/realtek: Re-order ALC269 Sony quirk table entries ALSA: hda/realtek: Re-order ALC269 ASUS quirk table entries ALSA: hda/realtek: Re-order ALC269 Dell quirk table entries ALSA: hda/realtek: Re-order ALC269 Acer quirk table entries ALSA: hda/realtek: Re-order ALC269 HP quirk table entries ALSA: hda/realtek: Re-order ALC882 Clevo quirk table entries ALSA: hda/realtek: Re-order ALC882 Sony quirk table entries ALSA: hda/realtek: Re-order ALC882 Acer quirk table entries ALSA: usb-audio: Remove redundant assignment to len ALSA: hda/realtek: Add quirk for Intel Clevo PCx0Dx ALSA: virtio: fix kernel-doc ALSA: hda/cirrus: Use CS8409 filter to fix abnormal sounds on Bullseye ALSA: hda/cirrus: Set Initial DMIC volume for Bullseye to -26 dB ALSA: sb: Fix two use after free in snd_sb_qsound_build ALSA: emu8000: Fix a use after free in snd_emu8000_create_mixer ...
