In particular the probe() and remove() callbacks of a device driver can get called at runtime when the device is hotplugged through sysfs. Arnd

When built into the kernel, the driver causes a link problem: `iproc_gpio_remove' referenced in section `.data' of drivers/gpio/gpio-xgs-iproc.o: defined in discarded section `.exit.text' of drivers/gpio/gpio-xgs-iproc.o Remove the incorrect annotation.
