Request_mem_region should be used with release_mem_region, not
release_resource.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@s exists@
expression e1,e2,e3,e4,e;
@@
*e4 = request_mem_region(e1,e2,e3)
... when != e4 = e
*release_resource(e4);
// </smpl>
