[git pull] Input updates for v4.17-rc7

[Dmitry Torokhov]

Hi Linus,

Please pull from:

	git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git for-linus

to receive updates for the input subsystem. We are switching a bunch of
Lenovo devices with Synaptics touchpads from PS/2 emulation over to
native RMI/SMbus.

Given that all commits are marked for stable there is no point delaying
them till next release.

Thanks!

Changelog:
---------

Aaron Ma (1):
      Input: synaptics - add Intertouch support on X1 Carbon 6th and X280

Benjamin Tissoires (2):
      Input: synaptics - add Lenovo 80 series ids to SMBus
      Input: elan_i2c_smbus - fix corrupted stack

Dmitry Torokhov (1):
      Input: synaptics - Lenovo Carbon X1 Gen5 (2017) devices should use RMI

Edvard Holst (1):
      Input: synaptics - Lenovo Thinkpad X1 Carbon G5 (2017) with Elantech trackpoints should use RMI

Hmm. The elan driver stack overrun isn't mentioned, but seems more
fundamental fix than the other changes that just add a few new PnP ID's...

I do not think that the Elan problem is actually observable on any
hardware with 4.17 at the moment, as it only shows up when switching
some Elan devices from PS/2 to SMBus and the patches that do that are
slated for the next merge window. I included it in the pull as a
precaution. Switching Synaptics to RMI is much more user-visible...

Still should have mentioned Elan corruption fix though.

Thanks.
