Variable acpi_video is global boolean (for this module) and when is set to true it is expected that ACPI generate brightness up/down key events via ACPI input device. When is acpi_video boolean variable is set to false then ACPI input device should not send brightness up/down keys to userspace. And dell-wmi.ko driver send those two keys via dell-wmi input device.
I know.
So please check that your change does not change above behaviour.
I've already checked this. > Maybe it would make sense to rename "acpi_video" variable to something better. There is another driver which has a similar construction. I believe that it would be good to add an acpi_video_handles_key_presses() helper to the acpi-video code which can be used for this instead of abusing acpi_video_get_backlight_type() for this. I've put this on my todo list to do as a further cleanup once the initial series is merged.
