/**
* __drm_atomic_get_current_plane_state - get current plane state
* @state: global atomic state object
* @plane: plane to grab
*
* This function returns the plane state for the given plane, either from
* @state, or if the plane isn't part of the atomic state update, from @plane.
* This is useful in atomic check callbacks, when drivers need to peek at, but
* not change, state of other planes, since it avoids threading an error code
* back up the call chain.
*
* WARNING:
*
* Note that this function is in general unsafe since it doesn't check for the
* required locking for access state structures. Drivers must ensure that it is
* safe to access the returned state structure through other means. One common
* example is when planes are fixed to a single CRTC, and the driver knows that
* the CRTC lock is held already. In that case holding the CRTC lock gives a
* read-lock on all planes connected to that CRTC. But if planes can be
* reassigned things get more tricky. In that case it's better to use
* drm_atomic_get_plane_state and wire up full error handling.
*
* Returns:
*
* Read-only pointer to the current plane state.
