    SubjectRe: [PATCH 22/58] move jazzsonic's probe function to .devinit.text
    From
    2009/3/28 Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:
    > A pointer to jazz_sonic_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.

    when I'm talking to journalists I just say "programmer" or something like that.
