Confirmed on 11.4 with samsung n220p (marvel plus) . Brightness scaling works,
but starts to scale down to the lowest/highest brightness available. Looks like
a keyboard event<->brightness scaling hooks issue. E.g. no key release sent.
The workarounds (force_release hack in sysfs) doesn't solve this here.
Mabye just a missing quirk in atkbd ?
