USB: gadget: Drop NULL test on list_entry result
list_entry, which is an alias for container_of, cannot return NULL, as there is no way to add a NULL value to a doubly linked list. A simplified version of the semantic match that findds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r@ expression x,E; statement S1,S2; position p,p1; @@ *x = list_entry@p(...) ... when != x = E *if@p1 (x == NULL) S1 else S2 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
