From 9ce9a123d9e70b764be3a3df92c61c2639b7acff Mon Sep 17 00:00:00 2001 From: Jason Gerecke Date: Fri, 11 Nov 2016 15:05:52 -0800 Subject: [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.
