[PATCH] rtc: goldfish: Use devm_platform_ioremap_resource() in goldfish_rtc_probe()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 21 Sep 2019 12:20:11 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
