Subject: [PATCH 08/10] qla2xxx: Fix qla2xxx_check_risc_status()
Date: Wed, 05 Jun 2013 15:08:29 +0200 [thread overview]
Message-ID: <51AF384D.2060209@acm.org> (raw)
In-Reply-To: <51AF36BF.3030602@acm.org>
Change the 'rval' variable from QLA_FUNCTION_TIMEOUT into QLA_SUCCESS
before starting a loop that is only executed if rval is initialized
to QLA_SUCCESS. Coverity reported that loop as "dead code".
