[PATCH] media: lm3646: remove redundant assignment to variable rval

[Colin King]

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

The variable rval is being initialized with 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: ("Unused value")
