[PATCH] fix ancient breakage in ebus_init()
Back when pci_dev had base_address[], loop of form base = &...->base_address[0]; for (.....) { ... *base++ = addr; } was fine, but when that array got spread in ->resource[...].start replacing the initialization with base = &...->resource[0].start; was not a sufficient modification. IOW this code got broken for cases when there had been more than one resource to fill. All way back in 2.3.41-pre3...
