[PATCH][RFC] Implement INSN_CONFIG_DIO_QUERY for PFI pins [WAS: Re: NI PCI-6025E: Mysterious subdevice #7]

Hi,

if the PFI pins on the NI 6025 board can be used for generic DIO it
makes sense to implement INSN_CONFIG_DIO_QUERY for those, too.
So I've tried and done the obvious. See attached patch.

Unfortunately, I don't have a very deep understanding of the driver and
ATM even haven't got a piece of hardware to test at hand. Moreover, a
quick glance at the E Series RLP Manual didn't show any examples where
the PFI pins are used for generic DIO.

So could anyone with a better understanding have a quick look and tell
me if these lines are correct or complete bullshit?

Thanks,
Jan
