On IBM Bartolo machines, cards in 00:09.0 are defunct (if use
interrupts). DSDT says that this slot (with function 0, i.e. pin A) is
routed to \_SB_.PCI0.PIB_.LNKB. But it's not, it's wired to LNKC, so
interrupts are misrouted. Add a quirk for this to workaround the
issue.

This error was reported in suse bugzilla at:
