But it missed that since the driver uses a shadow-buffered plane, the __drm_gem_{reset,duplicate,destroy}_shadow_plane() helper functions must be used in the struct drm_plane_funcs handlers. This was missed because the mentioned commit did not remove the macro DRM_GEM_SHADOW_PLANE_FUNCS, which leads to the custom plane's atomic state management handlers to not be used. Fixes: 45b58669e532 ("drm/ssd130x: Allocate buffer in the plane's .atomic_check() callback") Reported-by: Arnd Bergmann <arnd@xxxxxxxx>Reported-by needs to be followed by Closes: <url> where <url> would point to Arnd's bug report on dri-devel.Ah, I thought checkpatch complaining about it but since we already add a Link: with dim, didn't know what to add there. Makes sense to add Arnd's report indeed. I can include it when applying instead of posting a v2 if you don't mind.
Sure NP
