Yes. With status = "disabled" kernel completely ignores the device and struct device is not created at all even with the device being there. In general we're better off trying to probe the device and idle it. The only time we really want to mark something with status = "disabled" is if some coprocessor firmware is using that device and the kernel should not touch it at all.
