Subject: [patch v2] mpt2sas: issue reset is never uninitialized
Date: Thu, 4 Dec 2014 13:56:10 +0300 [thread overview]
Message-ID: <20141204105610.GA22643@mwanda> (raw)
The "issue_reset" variable can be used uninitialized. It should be set
to false at the start.
Also I cleaned up the types by using bool.
