Hi All,

Here is a series fixing the missing keypresses on some Panasonic Toughbook
models. These missing keypresses are caused by
commit ed83c9171829 ("platform/x86: panasonic-laptop: Resolve hotkey double
trigger bug"), which made the panasonic-laptop driver unconditionally drop
most WMI reported hotkeys.

This series reverts that commit and then adds some more selective filtering
to still avoid the double key-presses on some models, while avoiding
completely missing keypresses on others.

Rafael, these fixes rely on patch 1/7, which is a tweak to
the acpi_video_handles_brightness_key_presses() helper. Without this
tweak this series will cause a regression, so I would like to merge
the entire series through the pdx86 tree, may I have your ack for this?

Regards,

Hans
