Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation.
v3: - Update error handling for new drm_fb_helper funcs. Check using IS_ERR() instead of checking for NULL.
Reported-by: Dan Carpenter dan.carpenter@oracle.com
v2: - No changes
