Subject: [PATCH v4 02/11] software node: Make argument to to_software_node const
Date: Mon, 2 Sep 2019 11:32:31 +0300 [thread overview]
Message-ID: <20190902083240.20367-3-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20190902083240.20367-1-sakari.ailus@linux.intel.com>
to_software_node() does not need to modify the fwnode_handle it operates
on; therefore make it const. This allows passing a const fwnode_handle to
to_software_node().
