Subject: [PATCH 1/2] pwm: pwm-mxs: use devm_platform_ioremap_resource() to simplify code
Date: Tue, 24 Sep 2019 17:42:48 +0800 [thread overview]
Message-ID: <1569318169-12327-1-git-send-email-Anson.Huang@nxp.com> (raw)
Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.
