--------------------------------

[ Upstream commit 63cd736f ]

Some ATI SB600 USB adapters advertise MSI, but if INTx is disabled by
setting PCI_COMMAND_INTX_DISABLE, MSI doesn't work either.  The PCI/PCIe
specs do not require software to set PCI_COMMAND_INTX_DISABLE when enabling
MSI, but Linux has done that for many years.

Mick reported that 306c54d0 ("usb: hcd: Try MSI interrupts on PCI
devices") broke these devices.  Prior to 306c54d0, they used INTx.
Starting with 306c54d0, they use MSI, and and the fact that Linux sets
PCI_COMMAND_INTX_DISABLE means both INTx and MSI are disabled on these
devices.

Avoid this SB600 defect by disabling MSI so we use INTx as before.

Fixes: 306c54d0 ("usb: hcd: Try MSI interrupts on PCI devices")
