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

From: Colin King
Date: Wed Jun 12 2019 - 11:01:41 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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")
