| |
Pointers to s3c2410fb_probe and s3c2412fb_probe are passed to the core via platform_driver_register and so the functions must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to one of the drivers 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.
