From: Wayne Lin <Wayne.Lin@xxxxxxx>
This reverts commit 3c4d55c9b9becedd8d31a7c96783a364533713ab.
The reverted commit was trying to fix side effect brought by commit:
"3c4d55c9b9be drm/amd/display: turn DPMS off on connector unplug"
However,
* This reverted commit will have mst case never call dm_set_dpms_off()
which conflicts the idea of original commit: commit 3c4d55c9b9be
("drm/amd/display: turn DPMS off on connector unplug") That's due to
dm_crtc_state is always null since the input parameter aconnector is the
root device (source) of mst topology. It's not an end stream sink
within the mst topology.
* Setting dpms off should be triggered by usermode. Besdies, it seems
usermode does release relevant resource for mst & non-mst case when
unplug connecotr now. Which means we no longer need both commits now:
- commit 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector
unplug")
- commit 035f54969bb2 ("drm/amd/display: Add flag to detect dpms
force off during HPD")
