    platform-drivers: move probe to .devinit.text in drivers/video · c2e13037
    Uwe Kleine-König authored
    A pointer to a probe callback 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.
