ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node()
[ 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.
