Subject: media: lm3646: remove redundant assignment to variable rval
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ecfaec43e4999cb584135fccc09760be775b735c;p=openwrt%2Fstaging%2Fblogic.git

media: lm3646: remove redundant assignment to variable rval

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")
