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. So please check that your change does not change above behaviour. Maybe it would make sense to rename "acpi_video" variable to something better. -- Pali Rohár pali.rohar@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
