From: Jason Gerecke jason.gerecke@wacom.com Date: Tue, 7 May 2019 11:53:20 -0700 Subject: [PATCH] HID: wacom: Send BTN_TOUCH in response to INTUOSP2_BT eraser contact

The Bluetooth reports from the 2nd-gen Intuos Pro have separate bits for indicating if the tip or eraser is in contact with the tablet. At the moment, only the tip contact bit controls the state of the BTN_TOUCH event. This prevents the eraser from working as expected. This commit changes the driver to send BTN_TOUCH whenever either the tip or eraser contact bit is set.
