From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
First of all we should not be looking at fb->{width,height} as those do
not tell us what the actual pipe size is. Second of all we need to use
>= for the comparison.
So fix the comparison, and make use of the new pipe_src_{w,h} to
determine the real pipe source dimensions.
