Subject: drm/edid: Rename local variable block to edid
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f14f368670541bfa217573194027a58f2206e250;p=openwrt%2Fstaging%2Fblogic.git

drm/edid: Rename local variable block to edid

The "block" variable points to the entire edid, not individual blocks
despite it being named such.
