Subject: [PATCH] misc: cxl: Use device_type helpers to access the node type
Date:   Fri, 16 Nov 2018 16:11:02 -0600
Message-Id: <20181116221104.23024-6-robh@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Remove directly accessing device_node.type pointer and use the accessors
instead. This will eventually allow removing the type pointer.
