3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Bastian Triller <bastian.triller@xxxxxxxxx> commit c8f6d8351ba8c89d5cd4c562552ec7ec29274e31 upstream. Like on UL30VT, the ACPI video driver can't control backlight correctly on Asus UL30A. Vendor driver (asus-laptop) can work. This patch is to add "Asus UL30A" to ACPI video detect blacklist in order to use asus-laptop for video control on the "Asus UL30A" rather than ACPI video driver.
