[PATCH] media: platform: Use devm_platform_ioremap_resource() in two functions

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 18 Sep 2019 11:20:48 +0200

Simplify these function implementations by using a known wrapper function.

This issue was detected by using the Coccinelle software.
