Laxminarayan Bharadiya, Pankaj March 2, 2020, 4:21 p.m. UTC
drm_fb_helper_{add,remove}_one_connector() and
drm_fb_helper_single_add_all_connectors() are dummy functions now
and serve no purpose. Hence remove their calls.

This is the preparatory step for removing the
drm_fb_helper_{add,remove}_one_connector() functions from
drm_fb_helper.h

This removal is done using below sementic patch and unused variable
compilation warnings are fixed manually.
