[PATCH 3.4 29/44] ACPI / video: Add "Asus UL30VT" to ACPI video detect blacklist

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Lan Tianyu <tianyu.lan@xxxxxxxxx>

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.
