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

[Colin King]

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

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to do not much with it.

Thanks,
