Subject: [PATCH 4.6 42/96] Revert "Input: wacom_w8001 - drop use of ABS_MT_TOOL_TYPE"

4.6-stable review patch.  If anyone has any objections, please let me know.

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

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

commit 3e9161bfe0482f26efeaf584d5fd69398c69313c upstream.

This reverts commit 5f7e5445a2de848c66d2d80ba5479197e8287c33 because
removal of input_mt_report_slot_state() means we no longer generate
tracking IDs for the reported contacts.
