CVS commit: src/sys/external/bsd/drm2/radeon

[Chuck Silvers]

Module Name:    src
Committed By:   chs
Date:           Wed Nov 12 16:07:17 UTC 2014

Modified Files:
        src/sys/external/bsd/drm2/radeon: radeondrmkmsfb.c

Log Message:
apply several changes from intelfb.c revs 1.7 through 1.9:
 - provide a setmode callback for genfb
 - add a pmf shutdown handler to switch genfb into polling mode
 - no need to call drm_fb_helper_set_config after genfb attaches,
   as the setmode callback is called by genfb_attach
