Subject: [PATCH 6/6] dma: tegra20-apb-dma: remove unnecessary assignment
Date: Tue, 12 Feb 2013 12:58:39 +0200 [thread overview]
Message-ID: <1360666720-19006-7-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1360666720-19006-1-git-send-email-andriy.shevchenko@linux.intel.com>
There is no need to assign 0 to residue, because dma_cookie_status() does this
for us.
