Grr..
The error appears to be caused by the dma alloc/free in comedi_buf.c.
These only happen if the (s->async_dma_dir != DMA_NONE). The comedi
core defaults the async_dma_dir to DMA_NONE. The only comedi drivers
that set it are ni_660x, ni_mio_common, and ni_pcidio.
The mite driver also has a dma_alloc/free.
Ian, can you think of a better solution than just making comedi depend on HAS_DMA?
Thanks,
Hartley

The only alternative I can think of is to change comedi_buf.c to only
compile in the functions if CONFIG_HAS_DMA is defined and to make the
following config options depend on HAS_DMA:
COMEDI_NI_6527
COMEDI_NI_65XX
COMEDI_NI_660X
COMEDI_NI_670X
COMEDI_NI_LABPC_PCI
COMEDI_NI_PCIDIO
COMEDI_NI_PCIMIO
COMEDI_MITE
COMEDI_NI_TIOCMD
