Subject: [PATCH] drm/mcde: Make use of the helper function devm_platform_ioremap_resource()
Date: Tue, 31 Aug 2021 21:56:02 +0800	[thread overview]
Message-ID: <20210831135602.4476-1-caihuoqing@baidu.com> (raw)

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