FwupdPluginDeviceget_backend_parent_with_subsystem

Declaration [src]
FuDevice*
fu_device_get_backend_parent_with_subsystem (
  FuDevice* self,
  const gchar* subsystem,
  GError** error
)
Description [src]
Creates a device parent (of the correct type) using the current backend for a given device kind.
NOTE: The backend must implement FuBackendClass->get_device_parent for this method to work —
for cases where the plugin has created both parent and child, and used fu_device_add_child(), using fu_device_get_parent() is probably more appropriate.
Available since: 2.0.0
