drm/atomic: Move __drm_atomic_helper_disable_plane/set_config()
Prepare for moving drm_fb_helper modesetting code to drm_client. drm_client will be linked to drm.ko, so move __drm_atomic_helper_disable_plane() and __drm_atomic_helper_set_config() out of drm_kms_helper.ko. While at it, fix two checkpatch complaints: - WARNING: Block comments use a trailing */ on a separate line - CHECK: Alignment should match open parenthesis v7: Declare drm_mode_set and drm_plane_state Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Maxime Ripard <maxime.ripard@bootlin.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190531140117.37751-2-noralf@tronnes.org
