Subject: [PATCH net-next] net: moxa: Use devm_platform_get_and_ioremap_resource()
Date: Mon, 7 Jun 2021 23:02:59 +0800 [thread overview]
Message-ID: <20210607150259.4013977-1-yangyingliang@huawei.com> (raw)
Use devm_platform_get_and_ioremap_resource() to simplify
code and avoid a null-ptr-deref by checking 'res' in it.
