From: Ville Syrj?l? <ville.syrjala at linux.intel.com>
Use container_of() instead of a cast to get struct intel_fbdev
from struct drm_fb_helper.
Also populate the fb_info->par correctly with the drm_fb_helper pointer
instead of the intel_fbdev pointer.
There's no actual functional change since the drm_fb_helper happens to
be the first member inside intel_fbdev.
