From d3901eaf1fc289e8175faa8c7c460d542b6eb7dd Mon Sep 17 00:00:00 2001 From: Tarun Kanti DebBarma Date: Tue, 27 Sep 2011 05:38:09 +0530 Subject: [PATCH] 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.
