6.6-stable review patch. If anyone has any objections, please let me know.

From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com
[ Upstream commit c158cf914713efc3bcdc25680c7156c48c12ef6a ]
The documentation for device_get_named_child_node() mentions this important point:
" The caller is responsible for calling fwnode_handle_put() on the returned fwnode pointer. "
Add fwnode_handle_put() to avoid a leaked reference.
