Subject: [PATCH v3 13/24] dmaengine: edma: Use devm_kcalloc when possible
Date: Tue, 22 Sep 2015 12:54:24 +0300 [thread overview]
Message-ID: <1442915675-7121-14-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1442915675-7121-1-git-send-email-peter.ujfalusi@ti.com>
When allocating a memory for number of items it is better (looks better)
to use devm_kcalloc.
