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,
