I posted the same patch last month, along with two other patches that
fix the reporting for pre-r3.0 devices and simplify the code a bit:
http://marc.info/?l=linux-pci&m=135732663513525&w=2
http://marc.info/?l=linux-pci&m=135732713413779&w=2
http://marc.info/?l=linux-pci&m=135732666213542&w=2
I don't know the status of any of these; I'm expecting Dave to do
whatever he thinks is best.
