3.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Lan Tianyu <redacted> commit d0c2ce16bec0afa6013b4c5220ca4c9c67210215 upstream. The ACPI video driver can't control backlight correctly on Asus UL30VT. Vendor driver (asus-laptop) can work. This patch is to add "Asus UL30VT" to ACPI video detect blacklist in order to use asus-laptop for video control on the "Asus UL30VT" rather than ACPI video driver.
