Subject: [PATCH] keymap: Ignore brightness keys on Dell Inspiron 1520 to avoid

 double events

On the Dell Inspiron 1520 both the atkbd and acpi-video input devices report

an event for pressing the brightness up / down key-combos, resulting in user

space seeing double events and increasing / decreasing the brightness 2 steps

for each keypress.

This hwdb snippet suppresses the atkbd events, making the Inspiron 1520 work

like most modern laptops which emit brightness up / down events through

acpi-video only.
