I change the way of searching ISA node just because the platform driver
mechanism. Probe function of this driver will be called for each PCI
controller which means more than once. I think the Scott's way is not
perfectly match this situation. Anyway I will find a better way to solve
this by refactoring the Scott's method or using my own way.
