Subject: [PATCH V7 2/6] tty: serial: meson: Use devm_ioremap_resource to get register mapped memory
Date: Fri, 25 Feb 2022 15:39:18 +0800 [thread overview]
Message-ID: <20220225073922.3947-3-yu.tu@amlogic.com> (raw)
In-Reply-To: <20220225073922.3947-1-yu.tu@amlogic.com>
Replace devm_request_mem_region and devm_ioremap with
devm_ioremap_resource to make the code cleaner.
