FYI, removing all the ISA DMA support in this driver results in a
diffstat of:

 drivers/staging/comedi/drivers/ni_labpc.c | 207 ++--------------------------------------------------------
 drivers/staging/comedi/drivers/ni_labpc.h |   4 +-
 2 files changed, 5 insertions(+), 206 deletions(-)

It also remove the dependency on VIRT_TO_BUS which is
deprecated.
