Date: Thu, 2 Feb 2012 23:00:39 +0530 From: Tarun Kanti DebBarma <tarun.kanti@...com> To: <linux-omap@...r.kernel.org> CC: <grant.likely@...retlab.ca>, <khilman@...com>, <tony@...mide.com>, <linux-kernel@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, Tarun Kanti DebBarma <tarun.kanti@...com>, Charulatha V <charu@...com> Subject: [PATCH v9 13/25] gpio/omap: remove unnecessary bit-masking for read access Remove un-necessary bit masking. Since the register are 4 byte aligned and readl would work as is. The 'enabled' mask is already taking care to mask for bank width.
