Subject: [PATCH] media: sunxi: Make use of the helper function devm_platform_ioremap_resource()
Date:   Wed, 1 Sep 2021 13:56:53 +0800
Message-ID: <20210901055654.7979-1-caihuoqing@baidu.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

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