Subject: [PATCH v6 03/12] software node: Make argument to to_software_node const
Date: Tue, 10 Sep 2019 11:46:58 +0300 [thread overview]
Message-ID: <20190910084707.18380-4-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20190910084707.18380-1-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().
