Yes. However, in case of the function called by bus_for_each_drv(), it
should return zero if you want to continue or nonzero value to stop the
iteration.
I considered that if the probe fails, we can try with the next driver in
the list. So, the returned value of probe() is negated.
I will fix the other things and send it again with other suggestions.
Thanks,
