Subject: [PATCH v2] pmdomain: mediatek: Use devm_platform_ioremap_resource()
 in init_scp()

From: Markus Elfring <elfring@...rs.sourceforge.net>

Subject: [PATCH v2] pmdomain: mediatek: Use devm_platform_ioremap_resource() in init_scp()

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
