Subject: [PATCH -next] iio: adc: stm32-dfsdm: Use devm_platform_get_and_ioremap_resource()
Date: Fri, 18 Sep 2020 16:31:42 +0800 [thread overview]
Message-ID: <20200918083142.32816-1-bobo.shaobowang@huawei.com> (raw)
Make use of devm_platform_get_and_ioremap_resource() provided by
driver core platform instead of duplicated analogue, dev_err() is
removed because it has been done in devm_ioremap_resource().
