-stable review patch. If anyone has any objections, please let us know.
------------------
An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an
overly-zealous PCI quirk to only poke those VIA devices that need it.
However, some PCI devices were not included in what I hope is now the full
list. Consequently we're failing to run the quirk on all machines which need
it, causing IRQ routing failures.
This should I hope correct this.
Thanks to Masoud Sharbiani <[email protected]> for pointing this out
and testing the fix.
