Hi, just found that

echo 0000:06:01.0 > /sys/bus/pci/drivers/analogy_mite/unbind

does not do the same thing as

analogy_config -r analogyN

in fact it leaves the system in a state where using the driver results
in a kernel OOPS.

Will try to look into it further tomorrow...
Well, took quite some time to track down the 'analogy_config -r' bug (which was responsible for the kernel OOPS [i.e. after fixing it I have not got any OOPSes]).

So back to the original problem, does anybody foresee that a call to a4l_ioctl_devcfg(cxt, NULL) from the mite driver would give any problems (apart from getting the context pointer from the data structures the mite driver has handy)? It is probably not kosher to do ioctl on a driver that is not open, but...
