Subject: [PATCH] pwm: mxs: use devm_platform_ioremap_resource() to simplify code
Date: Thu, 18 Jul 2019 09:32:05 +0800	[thread overview]
Message-ID: <20190718013205.24919-1-Anson.Huang@nxp.com> (raw)

From: Anson Huang <Anson.Huang@nxp.com>

Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.
