Glue needs to be freed on exiting the function in an error case. Furthermore, pci, which is the first argument to the probe function should not be freed before leaveing the function, as it is reused at the call site. So the free of pci is changed to free glue instead. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
