monitor
[Fix]
Mario points out the commit in 6.7 may help
3b401e30c249 drm/ttm: Reorder sys manager cleanup step
[Test]
1. Build W7600 dGFx + Monitor: E2422H Config and FIDA Ubunutu22.04 OS.
2. Boot OS, put SUT to suspend.
3. Wake up the System from suspend.
4. Right away reboot the system from Ubuntu OS.
5. Put SUT to suspend and wake up the system.
6. After wake up Suspend, SUT should not be black screen.
7. Repetition Step 2~6 30 cycles
[Where problems could occur]
Handling the system memory manager after the workqueue is destroyed prevents
from the pointer beeing used after free. Should be pretty safe to include it.
