Is it necessary? If the list is empty, LIST_FOR_EACH_ENTRY will not loop
and status will be returned:
#define LIST_FOR_EACH_ENTRY_SAFE(pos, tmp, head, type, member) \
LIST_FOR_EACH_ENTRY(pos, head, type, member)
with:
#define LIST_FOR_EACH_ENTRY(pos, head, type, member) \
for ((pos) = (head)->lh_first ? \
container_of((head)->lh_first, struct type, member) : \
0; \
(pos); \
(pos) = (pos)->member.next.le_next ? \
container_of((pos)->member.next.le_next, struct type, \
member) : \
0)

Ditto, it should be removed.
