[PATCH 34/65] OMAPDSS: APPLY: rename manager_cache_data

Tomi Valkeinen
2011-11-22T09:23:50Z

manager_cache_data is not a suitable name for the struct. It is more of
a private data for the manager.

Rename the struct to mgr_priv_data, and add a function,
get_mgr_priv(mgr), to get a pointer to the data.
