While doing so is harmless for regular use, the missing device structure may be a problem for suspend to RAM support. Since, device links have been added to clocks, links created during probe will enforce the suspend/resume orders. When the device is missing during the registration, no link can be established, hence the order between parent and child clocks are not enforced. Adding the device structure here will create a link between the XTAL clock (this one) and the four TBG clocks that are derived from it.
