Add a helper function and make drivers that have the same logic in their struct drm_crtc_helper_funcs .atomic_check handler to use this instead. Patch #1, #2 and #3 are just cleanups for the mgag200, simpledrm and ssd130x drivers respectively. Finally patch #4 converts the last two drivers to use a helper instead of open coding it the same logic. The changes are inspired by a patch from Thomas Zimmermann for the ast DRM driver: https://patchwork.kernel.org/project/dri-devel/patch/20221010103625.19958-4-tzimmermann@xxxxxxx/ This is a v2 that addresses issues pointed out also by Thomas in v1: https://lists.freedesktop.org/archives/dri-devel/2022-October/375363.html Best regards, Javier Changes in v2: - Reference drm_plane_helper_atomic_check() from drm_crtc_atomic_check() kernel doc comments and viceversa (Thomas Zimmermann).
