[PATCH] ARM: zx: Use devm_platform_ioremap_resource() in zx296702_pd_probe()

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 18 Sep 2019 07:40:26 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
