Subject: gpio/omap: remove unnecessary bit-masking for read access
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d3901eaf1fc289e8175faa8c7c460d542b6eb7dd;p=linux-beck.git

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.
