Subject: pnpacpi-sets-pnpdev-devarchdata fix
From: David Brownell <david-b@xxxxxxxxxxx>
Handle PNP devices that have the same IDs a bit more sanely ... this at
least arranges multiple one-to-one mappings between PNP nodes and ACPI
nodes that all share the same PNP0c02 id. (Maybe mapped to the wrong node
though...)
This remains a hack, since it masks failures where PNP0a03 (a PCI root
bridge) is handled by ACPI special case code (/sys/devices/pci0000:00 on my
systems instead of /sys/devices/pnp0/pnp00:0/pci0000:00!) not pure PNPACPI
logic.
I suspect that pnp_dev.number and some acpi_device field need to be
compared, (so the right PNP0c02 nodes hook up to each other, PNP0a03
likewise) but I'll leave that to someone who knows how those ACPI table
lookups "should" work.
