From: Uwe Kleine-König on 23 Jan 2010 15:40 A pointer to w100fb_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.
