[PATCH 0/1] Failure to hibernate on Dell Latitude 7430

[David McFarland <corngood@gmail.com>]

I have a Dell Latitude 7430, and recently whenever I hibernate with
`systemctl hibernate`, the machine would immediately wake.

I bisected it to:

0c4cae1bc00d PM: hibernate: Avoid missing wakeup events during hibernation

However, the underlying problem seems to be that during hibernation, my
system gets a 0xcf (power button release) event, and the above change
causes it to abort hibernation correctly.

I also noticed that holding the power button down (when it's configured
to suspend) causes the system to suspend and then wake upon release, if
it's held long enough.

I'm attaching a patch which fixes the problem for me, by skipping the
wake on any of the release events.  These events are all marked
KEY_IGNORE, so think this is a reasonable thing to do.

I'm a little worried about the consequences of doing this
unconditionally in intel-hid.  Perhaps it should be a quirk?
