Subject: [PATCH 2/3] ACPI: Update the backlight state when we change brightness
Date: Mon, 13 Jul 2009 21:41:24 +0100 [thread overview]
Message-ID: <1247517685-7719-2-git-send-email-mjg@redhat.com> (raw)
In-Reply-To: <1247517685-7719-1-git-send-email-mjg@redhat.com>
Trigger a status update when we change the brightness in the driver, thus
allowing userspace to present appropriate UI.
