Subject: [media] it913x-fe: use ARRAY_SIZE() as a cleanup
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5359805193dc83e1aab2f8e230d57c649363c5c5;p=openwrt%2Fstaging%2Fblogic.git

[media] it913x-fe: use ARRAY_SIZE() as a cleanup

This code looks suspicious, but it turns out that "nv" is an array of u8
so sizeof() is the same as ARRAY_SIZE().  Using ARRAY_SIZE() is more
readable though.
