6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Leo Li sunpeng.li@amd.com
commit ef785ca7f7c80891580cafd36c8dd86375684310 upstream.
[Why]
There are more IPS modes other than DMUB_IPS_ENABLE that enables IPS. We need to enable the hotplug detect idle workqueue for those modes as well.
[How]
Modify the if condition to initialize the workqueue in all IPS modes except for DMUB_IPS_DISABLE_ALL.
