Subject: [PATCH] openrisc: Use common of_get_cpu_node() instead of open-coding
Date:   Mon, 27 Mar 2023 13:28:16 -0500
Message-Id: <20230327182816.233818-1-robh@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The common of_get_cpu_node() is equivalent to setup_find_cpu_node(), so
use it instead.
