Subject: [git pull] FireWire fixes post v3.3-rc1

Linus,

please pull from the tag "firewire-fixes" at

    git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394.git firewire-fixes

to receive workarounds table entries for hardware bugs in
  - FireWire part of Sound Blaster Audigy cards,
  - Ricoh PCIe 1394 controllers.
Without these, several protocols, e.g. AV/C, do not work on the
Audigy, and the Ricoh PCIe controllers wouldn't work at all.
This does not concern the older Ricoh PCI controllers.

    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.

    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.
