I think the other drivers that produce a similar warning usually
have a different bug, they have an incorrect of_match_ptr() or
ACPI_PTR() around the reference to that table, and the correct
fix is usually to just remove those macros. I have previously
sent patches for all of these, and could resend those.
These two pnp drivers are special because they predate the
linux-2.6 driver model and there is no reference to the table
at all in the drivers.
