Subject: drm: rcar-du: Replace plane crtc and enabled fields by plane state
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=47094194f070a5099854141bdbd54eae68e5ffd5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm: rcar-du: Replace plane crtc and enabled fields by plane state

The crtc and enabled fields duplicates information stored in the plane
state. Use the plane state instead and remove the fields.
