From: Takashi Iwai Date: Fri, 26 Jul 2019 09:42:34 +0000 (+0200) Subject: ALSA: hda - Show the fatal CORB/RIRB error more clearly X-Git-Tag: for-linus-2019-09-27~12^2~9^2~70 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=dd65f7e19c69;p=linux-block.git ALSA: hda - Show the fatal CORB/RIRB error more clearly The last fallback of CORB/RIRB communication error recovery is to turn on the single command mode, and this last resort usually means that something is really screwed up. Instead of a normal dev_err(), show the error more clearly with dev_WARN() with the caller stack trace. Also, show the bus-reset fallback also as an error, too.
