Subject: [Nouveau] [PATCH] nouveau: make backlight support non optional
Date: Sat, 24 Jul 2021 00:46:17 +0200 [thread overview]
Message-ID: <20210723224617.3088886-1-kherbst@redhat.com> (raw)
In the past this only led to compilation issues. Also the small amount of
extra .text shouldn't really matter compared to the entire nouveau driver
anyway.
