Subject: [PATCH v3 2/5] bus: hisi_lpc: Use devm_platform_ioremap_resource
Date: Mon, 5 Sep 2022 16:23:03 +0800 [thread overview]
Message-ID: <1662366186-233933-3-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1662366186-233933-1-git-send-email-john.garry@huawei.com>
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
The struct resource is not used for anything else, so we can simplify
the code a bit by using the helper function.
