3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: H Hartley Sweeten <hsweeten@visionengravers.com>

commit bd3a3cd6c27b117fb9a43a38c8072c95332beecc upstream.

Memory mapped io (dev->mmio) should not also be writing to the ioport
(dev->iobase) registers. Add the missing 'else' to these functions.

Fixes: 0953ee4acca0 ("staging: comedi: ni_mio_common: checkpatch.pl cleanup (else not useful)")
