From: Nicholas Kazlauskas Date: Mon, 28 Oct 2019 13:07:30 +0000 (-0400) Subject: drm/amd/display: Register DMUB service with DC X-Git-Tag: v5.6-rc1~114^2~21^2~359 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9a71c7d31734f74549ad2bcd652c403c71e7c8d1;p=thirdparty%2Fkernel%2Flinux.git 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.
