Subject[PATCH 44/70] ACPI / video: Add "Asus UL30VT" to ACPI video detect blacklist
Date
3.5.7.14 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lan Tianyu <tianyu.lan@intel.com>

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.
