[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...
