Hi all,
here is another patch which fixes a kernel warning where a subdevice is
released which no longer exists. The subdevice was removed before the
main comedi device. The functions for the main dev removal and the
subdevice were in different files/modules, were called from different
subsystems and I've moved them together to make sure the order is right.
There is still a problem that the subdevices are sometimes not generated
at boot time (cold boot) but hotplug does. I don't get any error
messages though so firmware load is probably not the problem. I've put
loads of the printk in it but then the error disappears (!). Seems to be
a very tight race condition.

Hi Bernd,
I won't be able to look at this until the new year, but it looks like it
will will break detachment via the COMEDI_DEVCONFIG ioctl (as used by
comedi_config -r /dev/comedi0). Also, I've no idea what git tree/branch
you're based on.
