[PATCH v2 09/29] ASoC: tas2764: Reinit cache on part reset

From: James Calligeros <hidden>
Date: 2025-02-18 08:37:05
Also in: asahi, linux-hwmon, linux-sound, lkml
Subsystem: sound, sound - soc layer / dynamic audio power management (asoc), texas instruments audio (asoc/hda) drivers, the rest · Maintainers: Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Shenghao Ding, Kevin Lu, Baojun Xu, Sen Wang, Linus Torvalds

From: Martin Povišer <povik+lin@cutebit.org>

When the part is reset in component_probe, do not forget to reinit the
regcache, otherwise the cache can get out of sync with the part's
actual state. This fix is similar to commit 0a0342ede303
("ASoC: tas2770: Reinit regcache on reset") which concerned the
tas2770 driver.

Fixes: 827ed8a0fa50 ("ASoC: tas2764: Add the driver for the TAS2764")
