Subject: [PATCH] watchdog: rti-wdt: Make use of the helper function devm_platform_ioremap_resource()
Date: Tue, 7 Sep 2021 15:42:36 +0800	[thread overview]
Message-ID: <20210907074237.2808-1-caihuoqing@baidu.com> (raw)

Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately
