Now I wanted to do not use i8042 hook function in dell-laptop.c which was used only for receiving key event (hw switch) and propagating it to dell-laptop rfkill device. See my patch: dell-laptop: Use dell-rbtn instead i8042 filter when possible But if we really should drop these atk key press, then another patch for it will be needed. -- Pali Rohár pali.rohar@xxxxxxxxx
