    Patch in this message
    Subject[PATCH] move mailbox's probe function to .devinit.text
    A pointer to omap2_mbox_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.
