staging: comedi: ni_mio_common: fix the ni_write[blw]() functions
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)") Cc: <stable@vger.kernel.org> # 3.17+ Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Reviewed-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
