[PATCH] move hgafb's probe function to .devinit.text

From: Uwe Kleine-KÃnig
Date: Sat Jul 11 2009 - 17:00:05 EST


A pointer to hgafb_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.
