The Description is a bit long winded and the same information is in

This member of the boardinfo is identical to the offset of the boardinfo
in the boardtypes array. It's also passed as the 'context' to the driver
(*auto_attach).
The 'cardtype' is only needed by the (*auto_attach) to determine which
PCI BAR to use and in pci_dio_reset() to handle the board specific code.
Remove the 'cardtype' member and use the 'context' value instead.

Currently the board reset function also resets the digital output channels
to 0. This works but it makes the reset function a bit messy and each
board type has to be handled special.

Interrupts are not used by this driver so the disable/clear during the

Currently the di/do subdevices store a pointer to the diosubd_data in s->private.
The (*insn_bits) functions then use that to get to the 'addr' needed to access

Currently the (*insn_bits) functions used the 'regs' member to determine how
many registers need to be read or written to update the subdevice. We can use
the subdevice 'n_chan' to determine this and make the code a bit clearer.
The (*auto_attach) also uses this member to determine how many 8255 devices
need to be initialized. These subdevices do not use the 'chans' member of
diosubd_data. Move the 'regs' value to the 'chans' to allow removing the
'regs' member completely.

The boards supported by this driver either use 8-bit or 16-bit I/O. The
'io_access' member of the boardinfo is used by the (*auto_attach) to

a bit-field flag 'is_16bit'. Use the new flag and remove the switch ()

ni_release_ai_mite_channel(), ni_release_ao_mite_channel(),
ni_release_gpct_mite_channel() and ni_release_cdo_mite_channel()
call functions which interpret -1 as a special value meaning "no channel".
This patch adds explicit "no_channel" versions instead.
On the other hand, after "no_channel" versions are used,
ni_set_ai_dma_channel(), ni_set_ao_dma_channel(),
ni_set_gpct_dma_channel(), ni_set_cdo_dma_channel() are called with actual
"channel" parameter being always unsigned, so their signatures are changed
accordingly.
A side benefit of the changes is suppressesing 4 sparse warnings:
"warning: shift too big (4294967295) for type int".
