Subject: drm/i915: Do not use plane_config in intel_fbdev.c
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8e9ba31a0f6c217e05f84efe9c569f9010a8ad26;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: Do not use plane_config in intel_fbdev.c

Use the atomic state instead, this allows removing plane_config
from the crtc after the full hw readout is completed.

The size can be found in the fb, no need for the plane_config.
