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.
Fixes: 6a41b6c5fc20 ("gpio: Add xgs-iproc driver")

What's the current best practice w.r.t.__init and __exit? I seem to
have messed this up on multiple fronts.

These are used for anything that is a module_init() function or a
module_exit() function, or called from one, but generally not
for any callbacks.
In particular the probe() and remove() callbacks of a device driver
can get called at runtime when the device is hotplugged through
sysfs.
