Pull sound fixes from Takashi Iwai: "Here are some piled fixes, hopefully the last big one for 5.11. All changes are device-specific small fixes, and majority of commits are for ASoC while USB-audio got a bit large changes for addressing the regression for devices with quirks" * tag 'sound-5.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (31 commits) ALSA: hda/hdmi - enable runtime pm for CI AMD display audio ALSA: firewire-tascam: Fix integer overflow in midi_port_work() ALSA: fireface: Fix integer overflow in transmit_midi_msg() ALSA: hda/tegra: fix tegra-hda on tegra30 soc clk: tegra30: Add hda clock default rates to clock driver ALSA: doc: Fix reference to mixart.rst ALSA: usb-audio: Fix implicit feedback sync setup for Pioneer devices ALSA: usb-audio: Annotate the endpoint index in audioformat ALSA: usb-audio: Avoid unnecessary interface re-setup ALSA: usb-audio: Choose audioformat of a counter-part substream ALSA: usb-audio: Fix the missing endpoints creations for quirks ALSA: hda/realtek: fix right sounds and mute/micmute LEDs for HP machines ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad X395 ASoC: amd: Replacing MSI with Legacy IRQ model ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad E14 Gen 2 ASoC: meson: axg-tdm-interface: fix loopback ASoC: meson: axg-tdmin: fix axg skew offset ASoC: max98373: don't access volatile registers in bias level off ASoC: rt711: mutex between calibration and power state changes ASoC: Intel: haswell: Add missing pm_ops ...
