Subject: [PATCH] can: flexcan: use devm_platform_ioremap_resource() to simplify code
Date: Sun, 29 Sep 2019 08:32:09 +0000 [thread overview]
Message-ID: <20190929082854.11952-1-qiangqing.zhang@nxp.com> (raw)
Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together to simplify
the code.
