sio_ite_8872_probe() bails out if it detects no-parallel (1S, 2S) or
unknown card.
It doesn't call release_region() on the previously allocated resource
though. This causes
(a) leak of the resource
(b) kernel oops when parport module is removed and /proc/ioports is read. This
is because the string that has been associated to the IO port region
is a static char array inside the already removed module.
Let's call release_region() properly before baling out.
