Subject: [PATCH] hwmon: (aspeed-pwm-tacho) Use devm_platform_ioremap_resource() in aspeed_pwm_tacho_probe()
Date: Wed, 18 Sep 2019 10:20:09 +0200 [thread overview]
Message-ID: <cd5bab7b-9333-2a43-bcf0-a47bbbe719eb@web.de> (raw)

Simplify this function implementation by using a known wrapper function.
This issue was detected by using the Coccinelle software.
