Subject: firewire: ohci: disable MSI on Ricoh controllers
From: Stefan Richter <[email protected]>
commit 320cfa6ce0b3dc794fedfa4bae54c0f65077234d upstream.
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/[email protected]/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.
