Pull sound fixes from Takashi Iwai: "Here are a few remaining patches for 6.1-rc1. The major changes are the hibernation fixes for HD-audio CS35L41 codec and the USB-audio small fixes against the last change. In addition, a couple of HD-audio regression fixes and a couple of potential mutex-deadlock fixes with OSS emulation in ALSA core side are seen" * tag 'sound-fix-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: hda: cs35l41: Support System Suspend ALSA: hda: cs35l41: Remove suspend/resume hda hooks ALSA: hda/cs_dsp_ctl: Fix mutex inversion when creating controls ALSA: hda: hda_cs_dsp_ctl: Ensure pwr_lock is held before reading/writing controls ALSA: hda: hda_cs_dsp_ctl: Minor clean and redundant code removal ALSA: oss: Fix potential deadlock at unregistration ALSA: rawmidi: Drop register_mutex in snd_rawmidi_free() ALSA: hda/realtek: Add Intel Reference SSID to support headset keys ALSA: hda/realtek: Add quirk for ASUS GV601R laptop ALSA: hda/realtek: Correct pin configs for ASUS G533Z ALSA: usb-audio: Avoid superfluous endpoint setup ALSA: usb-audio: Correct the return code from snd_usb_endpoint_set_params() ALSA: usb-audio: Apply mutex around snd_usb_endpoint_set_params() ALSA: usb-audio: Avoid unnecessary interface change at EP close ALSA: hda: Update register polling macros ALSA: hda/realtek: remove ALC289_FIXUP_DUAL_SPK for Dell 5530
