Subject: cciss: set default raid level when reading geometry fails
From: Mike Miller <mike.miller@xxxxxx>
Set a default raid level on a volume that either does not support reading the
geometry or reports an invalid geometry for whatever reason. We were always
setting some values for heads and sectors but never set a raid level. This
caused lots of problems on some buggy firmware. Please consider this for
inclusion.
