However, I think it'd be better to do the runtime_get/put in the caller, instead of in these dispc's wait funcs. While it doesn't really matter with dss_mgr_wait_for_vsync(), for dss_mgr/ovl_wait_for_go() it makes much more sense to get/put there just once, instead of every time the omap_dispc_wait_* is called.
