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

This line is needlessly long. Could you wrap it or shorten the SHA-1 ID?
You don't need more than the first 12 characters of the SHA-1 ID.

The same goes for this one. Please keep the width of the commit
description within 75 characters.

Apart from that the patch looks good.
