Subject: [PATCH 0/2] drm/amd/display: some backlight fixes
Date: Wed, 3 Feb 2021 13:42:39 +0100 [thread overview]
Message-ID: <20210203124241.8512-1-tiwai@suse.de> (raw)
Hi,
here are two patches handling the issues in the backlight control.
The first one is to fix the sysfs brightness read for devices with the
backlight controlled by aux channel. The second one is to add a new
module option, aux_backlight, to forcibly enable/disable the aux
channel backlight control. It's no direct solution for the bug we've
hit, but it gives at least a workaround.

thanks,
Takashi
