Subject: [RFC v4 06/25] drm/atomic: Move __drm_atomic_helper_disable_plane/set_config()
Date: Fri, 13 Apr 2018 18:53:35 +0200 [thread overview]
Message-ID: <20180413165354.8331-7-noralf@tronnes.org> (raw)
In-Reply-To: <20180413165354.8331-1-noralf@tronnes.org>
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.
