Subject: [ 14/21] ACPI / video: ignore BIOS initial backlight value for HP Pavilion g6
Date: Tue, 11 Jun 2013 13:03:08 -0700 [thread overview]
Message-ID: <20130611195521.662569695@linuxfoundation.org> (raw)
In-Reply-To: <20130611195520.003233586@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ash Willis <ashwillis.kernel@gmail.com>
commit 780a6ec640a3fed671fc2c40e4dd30c03eca3ac3 upstream.
This patch addresses kernel bug 56661. BIOS reports an incorrect
backlight value, causing the driver to switch off the backlight
completely during startup. This patch ignores the incorrect value from
BIOS.
