A wrapper function is available since the commit 7945f929f1a77a1c8887a97ca07f87626858ff42
("drivers: provide devm_platform_ioremap_resource()").
* Thus reuse existing functionality instead of keeping duplicate source code.
* Delete a local variable which became unnecessary with this refactoring.
This issue was transformed by using the Coccinelle software.

v2:
The transformation pattern was adjusted based on advices by known contributors.
Examples:
* Doug Anderson
* Geert Uytterhoeven
* Robin Murphy
