[PATCH v2 8/9] drm/bridge: put the bridge returned by drm_bridge_get_next_bridge()

[Luca Ceresoli]

The bridge returned by drm_bridge_get_next_bridge() is refcounted. Put it
when done. We need to ensure it is not put before either next_bridge or
next_bridge_state is in use, thus for simplicity use a cleanup action.

Signed-off-by: Luca Ceresoli <luca.ceres...@bootlin.com>

Changed in v2:
- use cleanup action instead of explicit drm_bridge_put(), also fixing the
  place where the ref is put
