[PATCH 0/2] Input: Add keycodes for electronic privacy screen on/off an use these in dell-wmi

[Hans de Goede <hansg@kernel.org>]

Hi All,

Here is a patch series for adding support for the electronic privacy screen
on/off events send on e.g. Dell Latitude 7300 models.

On these laptops the firmware does not allow querying the presence nor
the status of the eprivacy screen at boot. This makes it impossible to
implement the drm connector eprivacy properties API (1) since drm objects
do not allow adding new properties after creation and the presence of
the eprivacy cannot be detected at boot.

So instead this series adds 2 evdev keycodes for eprivacy screen on + off
and modifies the dell-wmi driver to use these, so that we can still
propagate these events to userspace for e.g. a DE to show an OSD.

Dmitry, can we get your ack for the addition of the 2 new keycodes?
I think it will be easiest if Ilpo merges the entire series through
the pdx86 tree with your ack for the keycodes.

Regards,

Hans
