From da45b381aafa8223fdb0b13e76e1dbf71f7d7c80 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Povi=C5=A1er?= Date: Sun, 6 Apr 2025 09:15:07 +1000 Subject: [PATCH] ASoC: tas2764: Reinit cache on part reset MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 592ab3936b096da5deb64d4c906edbeb989174d6 ] 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.
