Subject: drm/atomic: Pass the full state to CRTC atomic enable/disable
X-Git-Tag: accepted/tizen/unified/20230118.172025~6402^2~28^2~1651
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=351f950db4ab28c321a1bd4b92e4bb03e34c4703;p=platform%2Fkernel%2Flinux-rpi.git

drm/atomic: Pass the full state to CRTC atomic enable/disable

If the CRTC driver ever needs to access the full DRM state, it can't do so
at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state
will have cleared the pointer from the struct drm_crtc_state to the struct
drm_atomic_state before calling those hooks.

In order to allow that, let's pass the full DRM state to atomic_enable and
atomic_disable. The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.
