Subject: [PATCH 20/87] firewire: ohci: disable MSI on Ricoh controllers
|
|
|
|
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/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.
