2022-03-08ASoC: rt5668: do not block workqueue if card is unboundKai Vehmanen1-5/+7
[ Upstream commit a6d78661dc903d90a327892bbc34268f3a5f4b9c ] The current rt5668_jack_detect_handler() assumes the component and card will always show up and implements an infinite usleep loop waiting for them to show up. This does not hold true if a codec interrupt (or other event) occurs when the card is unbound. The codec driver's remove or shutdown functions cannot cancel the workqueue due to the wait loop. As a result, code can either end up blocking the workqueue, or hit a kernel oops when the card is freed. Fix the issue by rescheduling the jack detect handler in case the card is not ready. In case card never shows up, the shutdown/remove/suspend calls can now cancel the detect task.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There have been little changes in ALSA core stuff, but ASoC core still kept rolling for the continued restructuring. The rest are lots of small driver-specific changes and some minor API updates. Here are highlights: General: - Appropriate fall-through annotations everywhere - Some code cleanup in memalloc code, handling non-cacahed pages more commonly in the helper - Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently Drivers: - More HD-audio CA0132 codec improvement for supporting other Creative boards - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will give move support of existing HD-audio devices with DSP - A few device-specific HD-audio quirks as usual - New quirk for RME CC devices and correction for B&W PX for USB-audio - FireWire: code refactoring including devres usages ASoC Core: - Continued componentization works; it's almost done! - A bunch of new for_each_foo macros - Cleanups and fixes in DAPM code ASoC Drivers: - MCLK support for several different devices, including CS42L51, STM32 SAI, and MAX98373 - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and TI PCM3060" * tag 'sound-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (299 commits) ASoC: stm32: sai: fix master clock naming ASoC: stm32: add clock dependency for sai ALSA: hda/ca0132 - Actually fix microphone issue ASoC: sun4i-i2s: move code from startup/shutdown hooks into pm_runtime hooks ASoC: wm2000: Remove wm2000_read helper function ASoC: cs42l51: fix mclk support ASoC: wm_adsp: Log addresses as 8 digits in wm_adsp_buffer_populate ASoC: wm_adsp: Rename memory fields in wm_adsp_buffer ASoC: cs42l51: add mclk support ASoC: stm32: sai: set sai as mclk clock provider ASoC: dt-bindings: add mclk support to cs42l51 ASoC: dt-bindings: add mclk provider support to stm32 sai ASoC: soc-core: fix trivial checkpatch issues ASoC: dapm: Add support for hw_free on CODEC to CODEC links ASoC: Intel: kbl_da7219_max98927: minor white space clean up ALSA: i2c/cs8427: Fix int to char conversion ALSA: doc: Brush up the old writing-an-alsa-driver ASoC: rsnd: tidyup SSICR::SWSP for TDM ASoC: rsnd: enable TDM settings for SSI parent ASoC: pcm3168a: add hw constraint for capture channel ...

2018-09-07regmap: split up regmap_config.use_single_rwDavid Frey1-1/+2
Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.
