[PATCH 0/3] Add a drm_crtc_helper_atomic_check() helper

[Javier Martinez Canillas <javierm@redhat.com>]

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 and #2 are just cleanups for the simpledrm and ssd130x drivers
respectively, so that these can be converted to use the helper added by
patch #3. The changes are inspired by a patch from Thomas Zimmermann for
the ast DRM driver:

Best regards,
