Subject: [PATCH] ethernet: Use devm_platform_ioremap_resource() in three functions
Date: Wed, 18 Sep 2019 15:30:35 +0200	[thread overview]
Message-ID: <af65355e-c2f8-9142-4d0b-6903f23a98b2@web.de> (raw)

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 18 Sep 2019 15:15:06 +0200

Simplify these function implementations by using a known wrapper function.

This issue was detected by using the Coccinelle software.
