Subject[PATCH 3.16 152/233] HID: usbhid: Quirk a AMI virtual mouse and keyboard with ALWAYS_POLL
3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Colin Ian King <colin.king@canonical.com>

commit ed9ab4287f96e66340e0390e2c583f2f9110cba0 upstream.

Quirking the following AMI USB device with ALWAYS_POLL fixes an AMI
virtual keyboard and mouse from not responding and timing out when
it is attached to a ppc64el Power 8 system and when we have some
rapid open/closes on the mouse device.

usb 1-3: new high-speed USB device number 2 using xhci_hcd
usb 1-3: New USB device found, idVendor=046b, idProduct=ff01
usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-3: Product: Virtual Hub
usb 1-3: Manufacturer: American Megatrends Inc.
usb 1-3: SerialNumber: serial
usb 1-3.3: new high-speed USB device number 3 using xhci_hcd
usb 1-3.3: New USB device found, idVendor=046b, idProduct=ff31
usb 1-3.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-3.3: Product: Virtual HardDisk Device
usb 1-3.3: Manufacturer: American Megatrends Inc.
usb 1-3.4: new low-speed USB device number 4 using xhci_hcd
usb 1-3.4: New USB device found, idVendor=046b, idProduct=ff10
usb 1-3.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-3.4: Product: Virtual Keyboard and Mouse
usb 1-3.4: Manufacturer: American Megatrends Inc.

With the quirk I have not been able to trigger the issue with
half an hour of saturation soak testing.
