Subject: drm/i915: rip out superflous is_dp&is_cpu_edp tracking
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8b47047bd103c9fdb50440790a2ef17fa69a35c4;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: rip out superflous is_dp&is_cpu_edp tracking

The only exception left is is_cpu_edp in the haswell modeset code.
We need that to assign the cpu transcoder, but we might want to
move that eventually into the encoder, too.
