[PATCH v2 00/12] Remove redundant checks on existence of 'bridge->encoder'
The checks on the existence of bridge->encoder in the implementation of drm_bridge_funcs::attach() is not necessary, as it has already been checked in the drm_bridge_attach() function call by previous bridge or KMS driver. The drm_bridge_attach() will quit with a negative error code returned if it fails for some reasons, hence, it is guaranteed that the .encoder member of the drm_bridge instance is not NULL when various bridge attach functions are called.
