The "comedi_bond" driver can be used to map the DIO subdevices of some
other comedi devices into one, giant, uber DIO subdevice. However, it
has a few bugs such as memory leaks (but only if a memory allocation
fails), buffer overflow when more than 256 channels are added, not
handling `COMEDI_INSN_BITS` properly when there are more than 32
channels, and various other problems. Also it needs tidying up a bit
due to the use of CamelCase, etc.
Some of the changes involve changes to the "kcomedilib" module as well,
but that is only used by the "comedi_bond" module (for in-tree modules,
anyway, which is all we care about at the moment).

06) staging: comedi: comedi_bond: change return value of
bonding_attach()
07) staging: comedi: comedi_bond: use bitmap to record opened/closed
minors
08) staging: comedi: comedi_bond: don't map channels individually
09) staging: comedi: comedi_bond: remove unused subdev_type
10) staging: comedi: comedi_bond: no need to free dev->private on detach
11) staging: comedi: comedi_bond: just check devprivs->devs once on
detach
12) staging: comedi: comedi_bond: get INSN_CONFIG_DIO_QUERY info from
horse's mouth
13) staging: comedi: comedi_bond: handle base channel for insn_bits
14) staging: comedi: comedi_bond: use krealloc() and fix memory leak
15) staging: comedi: comedi_bond: use correct minor device numbers in
