[media] media: use entity.graph_obj.mdev instead of .parent
The struct media_entity has a .parent field that stores a pointer to the parent struct media_device. But recently a media_gobj was embedded into the entities and since struct media_gojb already has a pointer to a struct media_device in the .mdev field, the .parent field becomes redundant and can be removed. This patch replaces all the usage of .parent by .graph_obj.mdev so that field will become unused and can be removed on a later patch. No functional changes. The transformation was made using the following coccinelle spatch: @@ struct media_entity *me; @@ - me->parent + me->graph_obj.mdev @@ struct media_entity *link; @@ - link->source->entity->parent + link->source->entity->graph_obj.mdev @@ struct exynos_video_entity *ve; @@ - ve->vdev.entity.parent + ve->vdev.entity.graph_obj.mdev Suggested-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
