[char-msic 1/3] mei: me: disable driver on SPT SPS firmware

[Tomas Winkler]

commit 8c57cac1457f3125a5d13dc03635c0708c61bff0 upstream

Sunrise Point PCH with SPS Firmware doesn't expose working
MEI interface, we need to quirk it out.
The SPS Firmware is identifiable only on the first PCI function
of the device.

This is fix of the backported patch only, it places
KBL DIDs on correct place to easy on backporting of
further DIDs.

I don't understand what this is for, it's already in the 4.8-stable
tree.  And there you said it only needed to go to 4.6 and newer, yet you
are saying 4.4 here?  What am I supposed to do?

It's needed 4.4, but the original patch does apply cleanly only from 4.6 up, so this is the rebased version over 4.4. Since 4.4 is a long term kernel this is important.
I  see from time to time broken patches in stable,  mostly in 3.X series, so I prefer to do the back port myself.

The KBL DIDs were moved to a different part of the file during back port, than in the original patch hence the consequent 
patches will not apply cleanly.

 And what tree is this for?

What patch caused the ids to be moved around?  The one previous to this

It's not that automated as it is misspelled in this series :)

Anyway, stable would make more sense, char-misc 4.4 does not mean

Okay, will skip to that, Maybe Documentation/stable_kernel_rules.txt need some updates,
 also not sure you followed the mail thread regarding the git send-email issue

Your input will be valued.
