2024-08-06drm/amd/display: Replace dm_execute_dmub_cmd with dc_wake_and_execute_dmub_cmdRodrigo Siqueira1-2/+1
In the commit c2cec7a872b6 ("drm/amd/display: Wake DMCUB before sending a command for replay feature"), replaced dm_execute_dmub_cmd with dc_wake_and_execute_dmub_cmd in multiple areas, but due to merge issues the replacement of this function in the dmub_replay_copy_settings was missed. This commit replaces the old dm_execute_dmub_cmd with dc_wake_and_execute_dmub_cmd.
