Subject: [PATCH] mailbox: sun6i: Make use of the helper function devm_platform_ioremap_resource()
Date: Tue, 7 Sep 2021 15:42:00 +0800	[thread overview]
Message-ID: <20210907074201.2553-1-caihuoqing@baidu.com> (raw)

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