Hi, The new commit[1] will call acpi_video_dmi_promote_vendor() to add the ACPI_VIDEO_BACKLIGHT_DMI_VENDOR flag to acpi_video_support. So, asus-wmi.ko should be loaded before video.ko, or calling that function is in vain. Since loading video.ko will check those flags, we have to add the flag before it's being checked. I'm wondering is there a way to add this kind of dependency in the code, so that depmod will help to build the dependency in modules.dep 1. 272c77d asus-wmi: control backlight power through WMI, not ACPI Best regards, AceLan Kao. -- Chia-Lin Kao(AceLan) http://blog.acelan.idv.tw/ E-Mail: acelan.kaoATcanonical.com (s/AT/@/) -- 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
