[05/25] drm/fb_helper: Create a wrapper for fb_set_suspend

Commit Message

Archit Taneja July 13, 2015, 6:38 a.m. UTC

Some drm drivers call fb_set_suspend. Create a drm_fb_helper function
that wraps around these calls.

This is part of an effort to prevent drm drivers from calling fbdev
functions directly, in order to make fbdev emulation a top level drm
option.
