From c956798062b5a308db96e75157747291197f0378 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 8 Sep 2023 16:33:49 +0300 Subject: net: dsa: sja1105: propagate exact error code from sja1105_dynamic_config_poll_valid() Currently, sja1105_dynamic_config_wait_complete() returns either 0 or -ETIMEDOUT, because it just looks at the read_poll_timeout() return code. There will be future changes which move some more checks to sja1105_dynamic_config_poll_valid(). It is important that we propagate their exact return code (-ENOENT, -EINVAL), because callers of sja1105_dynamic_config_read() depend on them. Signed-off-by: Vladimir Oltean Signed-off-by: David S.
