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.
Regards,
Tony
