[PATCH][next] leds: lm36274: remove redundant initialization of variable ret

[Colin King <colin.king@canonical.com>]

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

The variable ret is being initialized with a value that is never
read, hence it is redundant and can be removed.  Also move the
declaration of ret to the for loop scope.

Addresses-Coverity: ("Unused value")
