[PATCH] hwmon: (aspeed-pwm-tacho) Use devm_platform_ioremap_resource() in aspeed_pwm_tacho_probe()

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 18 Sep 2019 10:12:31 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
