HID: add support for Sony RF receiver with USB product id 0x0374
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. # lsusb -vd 054C:0374 Bus 003 Device 002: ID 054c:0374 Sony Corp.
