From 9f9bc7d50437f11fecf5935ab91f44284e747222 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Wed, 14 Jul 2021 09:42:09 +0800 Subject: [PATCH] soundwire: bus: filter out more -EDATA errors on clock stop We've added quite a few filters to avoid throwing errors if a Device does not respond to commands during the clock stop sequences, but we missed one. This will lead to an isolated message [ 6115.294412] soundwire sdw-master-1: SDW_SCP_STAT bread failed:-61 The callers already filter this error code, so there's no point in keeping it at the lower level. Since this is a recoverable error, make this dev_err() conditional and only log cases with Command Failed.
