Subject: [patch v2] mpt3sas: issue_reset is uninitialized
Date: Thu, 04 Dec 2014 10:57:05 +0000 [thread overview]
Message-ID: <20141204105705.GB22643@mwanda> (raw)
In-Reply-To: <20141203100918.GA29583@mwanda>
The "issue_reset" can be used uninitialized. It should be set to false
at the start.
Also I cleaned up the types a little by using bool.

v2: style fix. use true/false instead of 1/0.
