Subject: [PATCH RESEND 1/3] hwspinlock: sirf: Change to use devm_platform_ioremap_resource()
Date:   Wed,  8 Jan 2020 11:23:44 +0800
Message-Id: <dfa043f317c609a6172468ac11598968dd751bce.1578453662.git.baolin.wang7@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together, which can simpify the code.
