Merge tag 'sound-5.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai: "Slightly bulky changes are seen at this time, mostly for dealing with the messed up Kconfig for ASoC Intel SOF stuff. The driver and its code was split to each module per platform now, which is far more straightforward. This should cover the randconfig problems, and more importantly, improve the actual device handling as well. Other than that, nothing particular stands out: the HDMI PCM assignment fix for Intel Tigerlake, MIPS n64 error handling fix, and the usual suspects, HD-audio / USB-audio quirks" * tag 'sound-5.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (21 commits) ALSA: hda/realtek: Apply dual codec quirks for MSI Godlike X570 board ALSA: hda/realtek: Add quirk for Intel NUC 10 ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically ALSA: hda/realtek: Add quirk for Clevo NH55RZQ ALSA: hda: intel-sdw-acpi: add missing include files ALSA: hda: move Intel SoundWire ACPI scan to dedicated module ASoC: SOF: Intel: SoundWire: simplify Kconfig ASoC: SOF: pci: move DSP_CONFIG use to platform-specific drivers ASoC: SOF: pci: split PCI into different drivers ASoC: SOF: ACPI: avoid reverse module dependency ASoC: soc-acpi: allow for partial match in parent name ALSA: hda: intel-nhlt: verify config type ALSA: hda: fix kernel-doc warnings ALSA: usb-audio: Fix Pioneer DJM devices URB_CONTROL request direction to set samplerate ALSA: usb-audio: use Corsair Virtuoso mapping for Corsair Virtuoso SE ALSA: hda/realtek: Enable headset mic of Acer SWIFT with ALC256 ALSA: ctxfi: cthw20k2: fix mask on conf to allow 4 bits ALSA: usb-audio: Allow modifying parameters with succeeding hw_params calls ALSA: usb-audio: Drop bogus dB range in too low level ALSA: usb-audio: Don't abort even if the clock rate differs ...
