Also, don't use of_match_ptr, it defines the table to NULL if
CONFIG_OF is not set, which breaks the ACPI based probing using
the magic number to tell it to use the DT bindings (weird
corner case). One of those really obscure corners cases
(and one that hasn't existed for that long!)
I'll fix up.
Applied to to the togreg branch of iio.git and pushed out as
testing for the autobuilders to play with it.
