Subject: drm/nouveau: Replace the iturbt_709 prop with the standard COLOR_ENCODING prop
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9aecbc45a3ceefe57f27ddc232e26e08513c9137;p=openwrt%2Fstaging%2Fblogic.git

drm/nouveau: Replace the iturbt_709 prop with the standard COLOR_ENCODING prop

Replace the ad-hoc iturbt_709 property with the new standard
COLOR_ENCODING property. Compiles, but not tested.

v2: Fix typos (Ilia)
