request_mem_region should be used when ioremap is used subsequently.
release_region is then correspondingly replaced by release_mem_region.
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
expression start,E;
@@
- request_region
+ request_mem_region
(start,...)
... when != request_mem_region(start,...)
when != start = E
ioremap(start,...)
@@
expression r.start;
@@
- release_region
+ release_mem_region
(start,...)
// </smpl>
