x86/PCI: Convert release_resource to release_region/release_mem_region
Request_region should be used with release_region, not release_resource.
The local variables region and region2 are dropped and the calls to
release_resource are replaced with calls to release_region, using the first
two arguments of the corresponding calls to request_region.
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>
