Subject: [PATCH v2 3/5] net: macb: Use devm_ioremap()
Date: Tue, 10 Dec 2013 16:07:21 -0800 [thread overview]
Message-ID: <1386720443-24100-4-git-send-email-soren.brinkmann@xilinx.com> (raw)
In-Reply-To: <1386720443-24100-1-git-send-email-soren.brinkmann@xilinx.com>
Use the device managed version of ioremap to remap IO memory,
simplifying error paths.
