3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason Gerecke <killertofu@xxxxxxxxx>
commit 33e5df0e0e32027866e9fb00451952998fc957f2 upstream.
It appears that the Cintiq Companion Hybrid does not send an ABS_MISC event to
userspace when any of its ExpressKeys are pressed. This is not strictly
necessary now that the pad exists on its own device, but should be fixed for
consistency's sake.
Traditionally both the stylus and pad shared the same device node, and
xf86-input-wacom would use ABS_MISC for disambiguation. Not sending this causes
the Hybrid to behave incorrectly with xf86-input-wacom beginning with its
8f44f3 commit.
