Merge tag 'sound-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "It's been a fairly calm development cycle. There are a few last-minute ALSA core fixes, most notably for covering PCM ioctl races, but the most of rest are device-specific changes. Below are some highlights: ALSA core: - Fixes for PCM ioctl races that may lead to UAF - Fix for oversized allocations in PCM OSS layer ASoC: - Start of moving SoF to support multiple IPC mechanisms - Use of NHLT ACPI table to reduce the amount of quirking required for Intel systems - Preliminary works forthcoming Intel AVS driver for legacy Intel DSP firmwares - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas RZ/V2L, Texas Instruments TAS585M HD-audio: - Driver re-binding fix for HD-audio - Updates for Intel ADL and Tegra234, various platform quirks for Dell, HP, Lenovo, ASUS, Samsung and Clevo machines USB-audio: - Quirk updates for Scarlett2, RODE, Corsair devices" * tag 'sound-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (486 commits) ALSA: hda/realtek: Add alc256-samsung-headphone fixup ALSA: pci: fix reading of swapped values from pcmreg in AC97 codec ALSA: pcm: Add stream lock during PCM reset ioctl operations ALSA: pcm: Fix races among concurrent prealloc proc writes ALSA: pcm: Fix races among concurrent prepare and hw_params/hw_free calls ALSA: pcm: Fix races among concurrent read/write and buffer changes ALSA: pcm: Fix races among concurrent hw_params and hw_free calls ASoC: atmel: mchp-pdmc: print the correct property name MAINTAINERS: Add Shengjiu to maintainer list of sound/soc/fsl ASoC: SOF: Add a new dai_get_clk topology IPC op ASoC: SOF: topology: Add ops for setting up and tearing down pipelines ASoC: SOF: expose sof_route_setup() ASoC: SOF: Add dai_link_fixup PCM op for IPC3 ASoC: SOF: Add trigger PCM op for IPC3 ASoC: SOF: Define hw_params PCM op for IPC3 ASoC: SOF: Introduce IPC3 PCM hw_free op ASoC: SOF: pcm: expose the sof_pcm_setup_connected_widgets() function ASoC: SOF: Introduce IPC-specific PCM ops ASoC: SOF: Add bytes_ext control IPC ops for IPC3 ASoC: SOF: Add bytes_get/put control IPC ops for IPC3 ...
