Almost all of the issues we so far needed patches for have been
addressed upstream with the exception of backlight probing.
The reason for this is detailled in the following bug:
https://bugs.freedesktop.org/show_bug.cgi?id=96571
In summary, when the I915 driver is built into the kernel, it can't
access the PWM because it's initialized at a later stage.
What we're now doing instead is that we compile i915 as a module and
bake the necessary PWM modules directly into the kernel.
This has the advantage that we no longer need the backlight.patch,
because after all this is already a workaround and having a workaround
that doesn't require us to rebase the patch once a new kernel arrives
seems to be a better solution in my opinion.
With this update we can now revert the reintroduction of kernel 4.12
done in 45bdcd7fc7788316cbad2d7d412e421b230715dc.

We can now safely drop the sound, sdio and drm patches, because they all
have been applied upstream already and after some testing the T100HA
works quite nicely.
One exception however is a small part from the drm patch, which is the
PMIC hack which I originally introduced in
e8861698f019eb218be451e444898a1cb5577d21 as a separate file which it's
now again, but rebased against kernel 4.12-rc6.

This is essentially a cherry-pick of the three commits mentioned in:
https://bugs.freedesktop.org/show_bug.cgi?id=97529#c33
Plus a backport against Linux 4.9 of the following patch:
https://bugs.freedesktop.org/attachment.cgi?id=128410
(essentially https://patchwork.freedesktop.org/series/16242/)
And also the backlight.patch (a PMIC hack) we had before all combined
into one patch, which now should fix the following bug:
https://bugs.freedesktop.org/show_bug.cgi?id=97529

This reverts commit 0182e0ca12760da2aecd65de98c85a76ecdcedc6.
With the latest testing kernel, the machine still gets random GPU
lockups which are already fixed in linux-next, so let's get back to
linux-next even though things break from time to time.
We can still pin a specific next version to base our patches on once we
have a base version that's stable enough.
I've also fixed the backlight patch to compile against the latest next
version.

Both of these patches are from the following Google Drive:
https://drive.google.com/folderview?id=0B4DiU2o72FbuejQ1S2VZZW5xV2c
The meta-keys-asus.patch (which is called just meta-keys.patch in this
repository) is used verbatim.
However, the baytrail-backlight.4.4.patch (here just backlight.patch) is
a rebased version of the patch from the Google Drive with a few
modifications by me, which boils down to:
* Remove the module parameter force_backlight_pmic, because this module
is hardware-specific so we don't actually need to do that (and *if*
we want to do that we'd compile it in directly).
* Add an unused pipe function argument to vlv_pmic_setup_backlight().
As the backlight patch introduces the functions intel_soc_pmic_readb()
and intel_soc_pmic_writeb() which are not available at module link time,
I have also added DRM_I915 to be compiled into the kernel.
In addition I needed to disable VIDEO_EM28XX and RAPIDIO, because they
do not compile with linux-next-20160226 and I didn't bother to provide
fixes because it's for hardware that is not existing on the T100HA.
Note that I'm using linux-next-20160226 here instead of 20160229 because
the latter has some networking I/O issues right now.
This makes the backlight, battery status and charging usable on the
T100HA and the fixes from the drm-intel-fixes branch are no longer
needed because they're already in linux-next-20160229.
