-Subject: software node: Introduce device_add_software_node()
-
-From: Heikki Krogerus <heikki.krogerus@linux.intel.com>
-
-[ Upstream commit e68d0119e3284334de5650a1ac42ef4e179f895e ]
-
-This helper will register a software node and then assign
-it to device at the same time. The function will also make
-sure that the device can't have more than one software node.
