drm: panel-lvds: Potential Oops in probe error handling
[ Upstream commit fb2ee9bf084bcaeff1e5be100decc0eacb4af2d5 ]
The "lvds->backlight" pointer could be NULL in situations where
of_parse_phandle() returns NULL. This code is cleaner if we use the
managed devm_of_find_backlight() so the clean up is automatic.
