| |
af_packet produces lots of these: net/packet/af_packet.c:384:39: warning: incorrect type in return expression (different modifiers) net/packet/af_packet.c:384:39: expected struct page [pure] * net/packet/af_packet.c:384:39: got struct page *
this seems to be because sparse does not realize that _pure refers to function, not the returned pointer.
Tweak code slightly to avoid the warning.
