From c36570970a585bc816e15478fde71476f96f5e9c Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Mon, 31 Jul 2023 17:57:19 +0100 Subject: [PATCH] ALSA: hda/cs35l56: Do not mark cache dirty after REINIT Only call regcache_mark_dirty() in cs35l56_hda_fw_load() if the CS35L56 was SYSTEM_RESET. recache_mark_dirty() changes the behaviour of regcache_sync() to write out cache values that are not the default value, and skip cache values that are the default. AUDIO_REINIT does not reset the registers. regcache_mark_dirty() after AUDIO_REINIT could cause the regcache_sync() to sync registers incorrectly because it will assume that all registers have reset to default.
