[PATCH v1 4/8] software node: Deduplicate code in fwnode_create_software_node()

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

Deduplicate conditional and assignment in fwnode_create_software_node(),
i.e. parent is checked in two out of three cases and parent software node
is assigned by to_swnode() call.
