[PATCH v9 13/25] gpio/omap: remove unnecessary bit-masking for read access

From: Tarun Kanti DebBarma
Date: Thu Feb 02 2012 - 12:33:03 EST


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.
