[PATCH v2 linux-next] ALSA: pcm: 'BUG:' message unnecessarily triggers kerneloops

From: Tim Gardner
Date: Wed Apr 16 2014 - 10:19:04 EST


BugLink: http://bugs.launchpad.net/bugs/1305480

The kerneloops-daemon scans dmesg for common crash signatures, among
which is 'BUG:'. The message emitted by the PCM library is really a
warning, so the most expedient thing to do seems to be to change the
string.

v2: Changed string preface from "OVER RUN" to "XRUN". As Takashi pointed out,
'Use a term "XRUN", as it's not always an overrun.'
