Subject[PATCH 4.14 23/31] HID: wacom: generic: Recognize WACOM_HID_WD_PEN as a type of pen collection
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Gerecke <killertofu@gmail.com>

commit 885e89f601a52cc6fb025b009df58ba83d142734 upstream.

The WACOM_PEN_FIELD macro is used to determine if a given HID field should be
associated with pen input. This field includes several known collection types
that Wacom pen data is contained in, but the WACOM_HID_WD_PEN application
collection type is notably missing. This can result in fields within this
kind of collection being completely ignored by the `wacom_usage_mapping`
function, preventing the later '*_event' functions from being notified about
changes to their value.

Fixes: c9c095874a ("HID: wacom: generic: Support and use 'Custom HID' mode and usages")
Fixes: ac2423c975 ("HID: wacom: generic: add vendor defined touch")
