Subject: [PATCH] iio: light: cm36651: redundant assignment to variable ret

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

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

Addresses-Coverity: ("Ununsed value")
