Subject: drm/i915: Stop using drm_atomic_helper_check_planes()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 131d3b1af10599b13c7bcd9bb137b5419cd12798
Patch-mainline: v5.5-rc1
References: bsc#1152489
We need to insert stuff between the plane and crtc .atomic_check()
drm_atomic_helper_check_planes() doesn't allow us to do that so
stop using it and hand roll the loops instead.
