drm/i915: set dummy page for stolen objects This is needed since currently sg_for_each_page assumes that we have a valid page in each sg item. It is only a real problem for CONFIG_SPARSEMEM where the page is dereferenced, in other cases the iterator works ok with an invalid page pointer. We can remove this workaround when we have fixed sg_page_iter to work on scatterlists without backing pages. Signed-off-by: Imre Deak <imre.deak@intel.com>
