p Busses implementing .Fn BUS_ADD_CHILD should insert the device into the tree using .Xr device_add_child 9 before adding things such as their own ivars and resource lists to the device. .Sh RETURN VALUES The .Fn BUS_ADD_CHILD method returns .Vt device_t added to the tree, or .Dv NULL . .Sh SEE ALSO .Xr device 9 , .Xr device_add_child 9 , .Xr driver 9 .Sh AUTHORS This manual page was written by .An M.
