[PARISC] Fix Cirrus 6832 Cardbus on RDI Tadpole PARISC Laptop
Fix irq-off-by-one for Cirrus 6832 Cardbus on RDI Tadpole PARISC Laptop. We just DECLARE_PCI_FIXUP_ENABLE as it is unlikely that this will be found in any other parisc system. Signed-off-by: Helge Deller <deller@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
