Merge tag 'sound-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Many updates in this development cycle are found in ASoC where it got a wide range of changes for the continued refactoring. Some highlights are below. ASoC: - Continued refactoring work by Morimoto-san toward the full componentization; the changes are seen allover the places - Support for force disconnecting muxes in DAPM - Continued development of ASoC Intel SOF stuff - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant CX2072X, Realtek RT1011 and RT1308 HD-audio: - More fixes and adjustments for ASoC SOF HD-audio - Fix for resume problem on some Realtek codecs USB-audio: - A few fixes for the issues reported by syzbot USB fuzzer - Fix for UAC2 extension unit parser - Quirks for Line6 Helix, Emgaic Unitor 8 FireWire: - Lots of code refactoring and fixes in most of its components" * tag 'sound-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (626 commits) ALSA: firewire-lib: code refactoring for local variables ALSA: firewire-lib: code refactoring for post operation to data block counter ALSA: firewire-lib: code refactoring for error path of parser for CIP header ALSA: firewire-lib: fix different data block counter between probed event and transferred isochronous packet ALSA: firewire-lib: fix initial value of data block count for IR context without CIP_DBC_IS_END_EVENT ALSA: firewire-lib/fireface: fix initial value of data block counter for IR context with CIP_NO_HEADER ALSA: firewire-lib: fix invalid length of rx packet payload for tracepoint events ALSA: usb-audio: fix Line6 Helix audio format rates firewire-motu: fix wrong reference count for stream functionality at error path of rawmidi interface ALSA: firewire-digi00x: fix wrong reference count for stream functionality at error path of rawmidi interface ALSA: dice: fix wrong reference count for stream functionality at error path of rawmidi interface ALSA: oxfw: fix wrong reference count for stream functionality at error path of rawmidi interface ALSA: fireworks: fix wrong reference count for stream functionality at error path of rawmidi interface ALSA: bebob: fix wrong reference count for stream functionality at error path of rawmidi interface ASoC: SOF: Intel: implement runtime idle for CNL/APL ASoC: SOF: add runtime idle callback ASoC: hdac_hdmi: report codec link up/down status to bus ASoC: SOF: debug: fix possible memory leak in sof_dfsentry_write() ASoC: sunxi: sun50i-codec-analog: Add earpiece ASoC: rt5665: remove redundant assignment to variable idx ...
