Subject: [PATCH] ASoC: codecs: realtek-soundwire: ignore initial PARITY errors
References: jsc#SLE-16518
Patch-mainline: v5.10-rc1
Git-commit: 38edbfae6c7f4ad402dd0464c1887eaf068468b8
The parity calculation is not reset on a Severe Reset, which leads to
misleading/harmless errors reported on startup. The addition of a
quirk helps filter out such errors while leaving the error checks on
in steady-state.
