[PATCH][next] pinctrl: ocelot: remove redundant assignment to variable ret

[Colin Ian King <colin.i.king@xxxxxxxxx>]

The variable ret is being assigned a value that is never read, it
is being re-assigned a value in every case statement in the following
switch statement. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
drivers/pinctrl/pinctrl-ocelot.c:1404:3: warning: Value stored to 'ret'
is never read [deadcode.DeadStores]
