[PATCH 1/2] net: dsa: vsc73xx: Use devm_platform_ioremap_resource() in vsc73xx_platform_probe()

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 20 Sep 2019 15:23:39 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
