The uevent support was initially added to handle systems where pressing a hotkey generates an event (good) but the firmware automatically changes the brightness (bad). I have absolutely no idea why I added BACKLIGHT_UPDATE_SYSFS - BACKLIGHT_UPDATE_HOTKEY solves the problem I was trying to solve. I'm not aware of any userspace that relies on BACKLIGHT_UPDATE_SYSFS. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- 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
