I made a small tweak.  This driver includes of.h to get
the ID table, which is less than ideal anyway.  Now you've added
a second table, I've switched that for mod_devicetable.h which is
the include that should have been used in the first place.

Applied with that and a not in the patch description to the togreg
branch of iio.git which is initially pushed out as testing for 0-day to
see if it can find anything we missed.

Thanks,

Jonathan
