This function is implemented as though the function of_get_next_child does not increment the reference count of its result, but actually it does. Thus the patch adds of_node_put in error handling code and drops a call to of_node_get. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E1; position p1,p2; @@ x@p1 = of_get_next_child(...); ... when != x = E1 of_node_get@p2(x) @script:python@ p1 << r.p1; p2 << r.p2; @@ cocci.print_main("call",p1) cocci.print_secs("get",p2) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Grant Likely <grant.likely@secretlab.ca> |
