firewire: ohci: fix regression with VIA VT6315, disable MSI
"VIA Technologies, Inc. VT6315 Series Firewire Controller [1106:3403]" does not generate any interrupts if Message Signaled Interrupts were enabled. This is a regression since kernel 2.6.36 in which MSI support was added to firewire-ohci. Hence blacklist MSI on all VIA controllers. Reported-by: Robin Cook <rcook@wyrms.net> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Cc: <stable@kernel.org> # 2.6.36.y
