[PATCH 05/19] drm: Allow the caller to pass in the format info to drm_helper_mode_fill_fb_struct()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Soon all drivers should have the format info already available in the
places where they call drm_helper_mode_fill_fb_struct(). Allow it to
be passed along into drm_helper_mode_fill_fb_struct() instead of doing
yet another redundant lookup.

Start by always passing in NULL and still doing the extra lookup.
The actual changes to avoid the lookup will follow.

Done with cocci (with some manual fixups):
