3.5.7.9 -stable review patch.  If anyone has any objections, please let me know.

commit a464918419f94a0043d2f549d6defb4c3f69f68a upstream.

Some Vaio desktop computers, among them the VGC-LN51JGB multimedia PC, have
a RF receiver, multi-interface USB device 054c:0374, that is used to connect
a wireless keyboard and a wireless mouse.

The keyboard works flawlessly, but the mouse (VGP-WMS3 in my case) does not
seem to be generating any pointer events. The problem is that the mouse pointer
is wrongly declared as a constant non-data variable in the report descriptor
(see lsusb and usbhid-dump output below), with the consequence that it is
ignored by the HID code.

Add this device to the have-special-driver list and fix up the report
descriptor in the Sony-specific driver which happens to already have a fixup
for a similar firmware bug.
