What I am against is removing of_match_ptr by doing a million
tiny patches.  Either we should keep it, in which case the
of_match_table field should be made conditional on OF or perhaps
a new Kconfig option if there is no way to reconcile this with
ACPI, or we decide to get rid of it and you should do one giant
patch to remove of_match_ptr across the kernel tree.

We should not be doing a patch for every single driver that has
of_match_table based on whether it can or cannot be used through
ACPI.
