Subject: [[PATCH v6 01/10] sparc/perf: Remove unnecessary assignment
Date: Thu, 3 Sep 2015 20:07:44 -0700 [thread overview]
Message-ID: <1441336073-22750-2-git-send-email-sukadev@linux.vnet.ibm.com> (raw)
In-Reply-To: <1441336073-22750-1-git-send-email-sukadev@linux.vnet.ibm.com>
In ->commit_txn() 'cpuc' is already initialized when it is
declared, so we can remove the duplicate assignment.
