Subject: [PATCH 1/2] firewire: ohci: add reset packet quirk for SB Audigy
The Audigy's SB1394 controller is actually from Texas Instruments
and has the same bus reset packet generation bug, so it needs the
same quirk entry.

Subject: [PATCH 2/2] firewire: ohci: disable MSI on Ricoh controllers
The PCIe device
FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd FireWire Host Controller
[1180:e832] (prog-if 10 [OHCI])
is unable to access attached FireWire devices when MSI is enabled but
works if MSI is disabled.
http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28251.html
Hence add the "disable MSI" quirks flag for this device, or in fact for
safety and simplicity for all current (R5U230, R5U231, R5U240) and
future Ricoh PCIe 1394 controllers.
