Ah ok, fair enough, I thought it was merged. In any case, after thinking
about it, it wouldn't have helped.

My concern is if we can avoid changing the TIMER_OF_DECLARE because of
the boot order, it would be better.

Can returning EPROBE_DEFER fix this issue? Or use the 'complex
dependencies' [1]?

I'm pretty busy ATM, so I can not investigate now if the suggestions
above are fine or just stupid. I will have a look as soon as I can.
