[V8,02/14] drm/bridge: do not pass drm_bridge_funcs to drm_bridge_init

Commit Message

Ajay Kumar Nov. 15, 2014, 9:54 a.m. UTC

Assign the pointer to bridge ops structure(drm_bridge_funcs) in
the bridge driver itself, instead of passing it to drm_bridge_init.

This will allow bridge driver developer to pack bridge private
information inside the bridge object and pass only the drm-relevant
information to drm_bridge_init.
