Mario Limonciello (AMD) 60f71f0db7 drm/amd/display: Drop dm_prepare_suspend() and dm_complete() ... [Why] dm_prepare_suspend() was added in commit 50e0bae34f ("drm/amd/display: Add and use new dm_prepare_suspend() callback") to allow display to turn off earlier in the suspend sequence. This caused a regression that HDMI audio sometimes didn't work properly after resume unless audio was playing during suspend. [How] Drop dm_prepare_suspend() callback. All code in it will still run during dm_suspend(). Also drop unnecessary dm_complete() callback. dm_complete() was used for failed prepare and also for any case of successful resume. The code in it already runs in dm_resume(). This change will introduce more time that the display is turned on during suspend sequence. The compositor can turn it off sooner if desired.
