commit 1d90d6d5522befa8efa1a7ea406be65cf865ded4 upstream.

Without this the aux port does not get detected, and consequently the touchpad
will not work.

With this patch the touchpad is detected:

commit 148e9a711e034e06310a8c36b64957934ebe30f2 upstream.

On some laptops, keyboard needs to be reset in order to successfully detect
touchpad (e.g., some Gigabyte laptop models with Elantech touchpads).
Without resettin keyboard touchpad pretends to be completely dead.

Based on the original patch by Mateusz Jończyk this version has been
expanded to include DMI based detection &amp; application of the fix
automatically on the affected models of laptops. This has been confirmed to
fix problem by three users already on three different models of laptops.

<title>Input: xpad - use proper endpoint type</title>

commit a1f9a4072655843fc03186acbad65990cc05dd2d upstream.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.

commit e4742b1e786ca386e88e6cfb2801e14e15e365cd upstream.

The new Lenovo T440s laptop has a different PnP ID "LEN0039", and it
needs the similar min/max quirk to make its clickpad working.

commit d49cb7aeebb974713f9f7ab2991352d3050b095b upstream.

commit 421e08c41fda fixed the reported min/max for the X and Y axis,
but unfortunately, it broke the resolution of those same axis.

On the t540p, the resolution is the same regarding X and Y. It is not
a problem for xf86-input-synaptics because this driver is only interested
in the ratio between X and Y.
Unfortunately, xf86-input-cmt uses directly the resolution, and having a
null resolution leads to some divide by 0 errors, which are translated by
-infinity in the resulting coordinates.

commit 0f68f39c393bc06ac5ccc8794f0e2ed841e41c3e upstream.

Most of the affected models share pnp-ids for the touchpad. So switching
to pnp-ids give us 2 advantages:
1) It shrinks the quirk list
2) It will lower the new quirk addition frequency, ie the recently added W540
   quirk would not have been necessary since it uses the same LEN0034 pnp ids
   as other models already added before it

As an added bonus it actually puts the quirk on the actual psmouse, rather
then on the machine, which is technically more correct.
