2009/3/28 Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>:
A pointer to mac_sonic_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

mac_{onboard,nubus}_sonic_probe() (called by mac_sonic_probe()) have the
same problem.
