[PATCH v2] bus: omap_l3_noc: Use devm_platform_ioremap_resource() in omap_l3_probe()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 6 Feb 2024 17:01:25 +0100

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
