Subject: [PATCH] PCI: mediatek-gen3: Make use of the helper function devm_platform_ioremap_resource_byname()
Date: Wed, 1 Sep 2021 15:40:06 +0800 [thread overview]
Message-ID: <20210901074006.8783-1-caihuoqing@baidu.com> (raw)
Use the devm_platform_ioremap_resource_byname() helper instead of
calling platform_get_resource_byname() and devm_ioremap_resource()
separately
