Reimplement a call to devm_request_mem_region followed by a call to ioremap
or ioremap_nocache by a call to devm_request_and_ioremap.
The semantic patch that makes this transformation is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@nm@
expression myname;
identifier i;
@@
struct platform_driver i = { .driver = { .name = myname } };
@@
expression dev,res,size;
expression nm.myname;
@@
-if (!devm_request_mem_region(dev, res->start, size,
- \(res->name\|dev_name(dev)\|myname\))) {
- ...
- return ...;
-}
... when != res->start
(
-devm_ioremap(dev,res->start,size)
+devm_request_and_ioremap(dev,res)
|
-devm_ioremap_nocache(dev,res->start,size)
+devm_request_and_ioremap(dev,res)
)
... when any
when != res->start
// </smpl>

Pushed to l2-mtd-2.6.git, thanks!
I think this semantic patch is also useful and deserves to be added to
scripts/coccinelle. In general, it would be great if you sumbitted
useful spatches there for inclusion.
OK, I will add this one as well.
