Subject: [PATCH] watchdog: imx2_wdt: use devm_platform_ioremap_resource() to simplify code
Date: Mon, 1 Apr 2019 05:04:30 +0000	[thread overview]
Message-ID: <1554094787-14766-1-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.
