Subject: [PATCH] iio: adc: rockchip_saradc: Make use of the helper function devm_platform_ioremap_resource()
Date: Wed, 8 Sep 2021 18:56:30 +0800 [thread overview]
Message-ID: <20210908105631.1474-1-caihuoqing@baidu.com> (raw)
Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately
