Merge tag 'sound-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai: "As usual in a late stage, we received a fair amount of fixes for ASoC, and it became bigger than wished. But all fixes are rather device- specific, and they look pretty safe to apply. A major par of changes are series of fixes for ASoC meson and SOF drivers as well as for Realtek and Cirrus codecs. In addition, recent emu10k1 regression fixes and usual HD-audio quirks are included" * tag 'sound-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (46 commits) ALSA: hda/realtek: Fix build error without CONFIG_PM ALSA: hda/realtek: Fix conflicting PCI SSID 17aa:386f for Lenovo Legion models ALSA: hda/realtek - Set GPIO3 to default at S4 state for Thinkpad with ALC1318 ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node() ALSA: hda: intel-dsp-config: harden I2C/I2S codec detection ASoC: cs35l56: fix usages of device_get_named_child_node() ASoC: da7219-aad: fix usage of device_get_named_child_node() ASoC: meson: cards: select SND_DYNAMIC_MINORS ASoC: meson: axg-tdm: add continuous clock support ASoC: meson: axg-tdm-interface: manage formatters in trigger ASoC: meson: axg-card: make links nonatomic ASoC: meson: axg-fifo: use threaded irq to check periods ALSA: hda/realtek: Fix mute led of HP Laptop 15-da3001TU ALSA: emu10k1: make E-MU FPGA writes potentially more reliable ALSA: emu10k1: fix E-MU dock initialization ALSA: emu10k1: use mutex for E-MU FPGA access locking ALSA: emu10k1: move the whole GPIO event handling to the workqueue ALSA: emu10k1: factor out snd_emu1010_load_dock_firmware() ALSA: emu10k1: fix E-MU card dock presence monitoring ASoC: rt715-sdca: volume step modification ...
