Subject: [PATCH 1/3] drivers/mmc/host/mvsdio.c: Convert release_resource to release_mem_region

Request_mem_region should be used with release_mem_region, not
release_resource.

A semantic patch that partially fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@b@
expression x,E;
@@

x = request_mem_region(x->start,...)
... when != release_mem_region(x->start,...)
    when != x = E
(
- release_resource(x);
- kfree(x);
+  release_mem_region(x->start,resource_size(x));
|
?- release_resource(x);
+  release_mem_region(x->start,resource_size(x));
)
// </smpl>
