[PATCH] soc: mdediatek: devapc: use devm_platform_ioremap_resource() instead of of_iomap()

From: zhengkang huang
Date: Fri Apr 14 2023 - 05:23:25 EST


In mtk_devapc_probe(), if of_iomap succeeds and any following error occurs,
it needs to deallocate the resource.

Fix this by repalcing of_iomap with devm_platform_ioremap_resource, which
automatically self-manages the resource. This can avoid modifying error
handling code.
