Subject: [PATCH 0/5] Convert release_resource to release_region/release_mem_region

Request_region should be used with release_region, not release_resource.

The changes are somewhat complicated, so I have only done a few cases to
start with.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,E;
@@
(
*x = request_region(...)
|
*x = request_mem_region(...)
)
... when != release_region(x)
    when != x = E
* release_resource(x);
// </smpl>

The complete set of files in which this semantic match finds problesm is as
follows:
