From 0a0342ede303fc420f3a388e1ae82da3ae8ff6bd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Povi=C5=A1er?= Date: Mon, 19 Sep 2022 19:34:53 +0200 Subject: ASoC: tas2770: Reinit regcache on reset MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On probe of the ASoC component, the device is reset but the regcache is retained. This means the regcache gets out of sync if the codec is rebound to a sound card for a second time. Fix it by reinitializing the regcache to defaults after the device is reset.
