- Remove objects from evict list when re-validated
- Bunch of corner case and error path fixes
- DPU:
- Dropped dev_pm_opp_set_rate(0) preventing burnout
- Fixed SSPP offsets of Kaanapali
- DP:
- Dropped dev_pm_opp_set_rate(0) preventing burnout
- Cleaned up core code in preparation for MST support
- Fixed prepare() to let Pipewire continue in case of the unplugged cable
