drm_atomic_get_mst_topology_state —
struct drm_dp_mst_topology_state * drm_atomic_get_mst_topology_state ( | struct drm_atomic_state * state, |
struct drm_dp_mst_topology_mgr * mgr) ; |
This function wraps drm_atomic_get_priv_obj_state
passing in the MST atomic
state vtable so that the private object state returned is that of a MST
topology object. Also, drm_atomic_get_private_obj_state
expects the caller
to care of the locking, so warn if don't hold the connection_mutex.
