Subject: [PATCH 1/3] drivers/net/ariadne.c: Convert release_resource to release_region/release_mem_region
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>
@@
expression x,E;
@@
*x = request_mem_region(...)
... when != release_mem_region(x)
when != x = E
* release_resource(x);
// </smpl>
