Subject: [PATCH v2 6/6] dma: tegra20-apb-dma: remove unnecessary assignment
Date: Thu, 14 Feb 2013 11:00:20 +0200 [thread overview]
Message-ID: <1360832420-6349-7-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1360832420-6349-1-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.
