Subject: [PATCH -next] can: ti_hecc: use devm_platform_ioremap_resource_byname
Date: Thu, 17 Sep 2020 14:36:34 +0800 [thread overview]
Message-ID: <20200917063634.2183792-1-wangxiaojun11@huawei.com> (raw)
Use the devm_platform_ioremap_resource_byname() helper instead of
calling platform_get_resource_byname() and devm_ioremap_resource()
separately.
