Subject: [PATCH] iio: dac: stm32-dac:  Make use of the helper function devm_platform_ioremap_resource()
Date:   Wed, 8 Sep 2021 18:56:38 +0800
Message-ID: <20210908105638.1525-1-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
