From 5f8b8c91bfa83debf11fe47831bc49973942349f Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Mon, 28 Oct 2019 09:07:30 -0400 Subject: [PATCH 4332/4736] drm/amd/display: Register DMUB service with DC [Why] DC can utilize the DMUB server to send commands to the DMUB but it's the DM responsibility to pass it the service to use. [How] Create the dc_dmub_srv after we finish initializing the dmub_srv. Cleanup the dc_dmub_srv before destroying the dmub_srv or dc.
