Subject: [PATCH] media: platform: Use devm_platform_ioremap_resource() in two functions
Date: Wed, 18 Sep 2019 11:30:30 +0200	[thread overview]
Message-ID: <d80a685a-c3de-b9c9-ad32-e1da9308c393@web.de> (raw)

From: Markus Elfring <elfring@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.
