Pull device properties framework updates from Rafael Wysocki: "These make the fwnode_handle_get() function return a pointer to the target fwnode object, which reflects the of_node_get() behavior, and add a macro for iterating over graph endpoints (Sakari Ailus)" * tag 'devprop-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: device property: Add a macro for interating over graph endpoints device property: Make fwnode_handle_get() return the fwnode
