Subject: [PATCH][next] gpio: bd70528: remove redundant assignment to variable ret

From: Colin Ian King <colin.king@...onical.com>

Variable ret is being initialized with a value that is never read
and ret is being re-assigned a little later on. The assignment is
redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
