Re: [PATCH] HID: wacom: Declare tool ID 0x84a as an Intuos eraser

The eraser end of the 8K pen available for the MobileStudio Pro has a tool
ID of 0x84a. The 'wacom_intuos_get_tool_type' function does not currently
recognize this ID, causing it to return BTN_TOOL_PEN rather than
BTN_TOOL_RUBBER. This does not cause a problem for the MobileStudio Pro
since, as a HID_GENERIC device, the driver relies on the state of the
HID_DG_INVERT usage instead. It would, however, cause problems if the pen
is used with devices that use the traditional 'wacom_intuos_irq' codepath
instead.
