It seems that the WMI GUID used by the PEAQ 2-in-1 WMI hotkeys is not
as unique as a GUID should be and is used on some other devices too.

This is causing spurious key-press reports on these other devices.

This commits adds a DMI check to the PEAQ 2-in-1 WMI hotkeys driver to
ensure that it is actually running on a PEAQ 2-in-1, fixing the
spurious key-presses on these other devices.


Recently I have pushed similar patch (another device). Can you rebase
against testing?


That patch adds a blacklist, for yet another model then the 2 bugreports:

BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1497861
BugLink: https://bugzilla.suse.com/attachment.cgi?id=743182


which I've received. My patch adds a whitelist instead as it seems the GUID
used is some very generic GUID,

Since you are maintainer and moreover have a hardware to test I assume
that's correct thing to do...

so the blacklist patch should simply be
dropped,

... however, the patch can't be dropped.

Either me, or you in v2 need to revert it. Tell me what you prefer here.

Isn't the whole purpose of having a testing branch that patches can
actually be dropped. AFAIK this has not even hit -next yet, so IMHO
it should just be dropped ?

If it really should be reverted instead I'll leave doing a revert up
to you.

In any case, please (re)send with Cc to Kai so he or bug reportes may
have a chance to test it as well.

Ok, done.

Hans
