From: Shaohui Xie <shaohui....@freescale.com>
When probing devices-in-package for a c45 phy, device zero is the last
device to probe, in a rare situation which driver can read a '0' from
the device zero, thus c45_ids->devices_in_package is set to '0', so the
loop condition of probing is matched, see codes below:
for (i = 1;i < num_ids && c45_ids->devices_in_package == 0;i++)
driver will run in a dead loop.
So after probing the device zero, driver should stop the probing loop.
