include/linux/memremap.h:258:9: warning: expression which evaluates to zero treated as a null pointer constant of type 'struct folio *'
...because I failed to update the pgmap_request_folio() return value in
the CONFIG_ZONE_DEVICE=n case when changing the calling convention.
Fixes: e634e7e18f3b ("mm/memremap: Introduce pgmap_request_folio() using pgmap offsets")
