[PATCH 3.4 30/44] ACPI / video: Add "Asus UL30A" to ACPI video detect blacklist

From: Greg Kroah-Hartman
Date: Mon Jul 07 2014 - 20:07:17 EST


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.
