[PATCH 4.19 03/18] platform/x86: intel-hid: Support Lenovo ThinkPad X1 Tablet Gen 2

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Alban Bedel <albeu@free.fr>

[ Upstream commit 56678a5f44ef5f0ad9a67194bbee2280c6286534 ]

Like a few other system the Lenovo ThinkPad X1 Tablet Gen 2 miss the
HEBC method, which prevent the power button from working. Add a quirk
to enable the button array on this system family and fix the power
button.
