drm/amd/pm: fix race in power state check before mutex lock

2026-01-27T23:25:15Z

The power state check in amdgpu_dpm_set_powergating_by_smu() is done before acquiring the pm mutex, leading to a race condition where: 1. Thread A checks state and thinks no change is needed 2. Thread B acquires mutex and modifies the state 3. Thread A returns without updating state, causing inconsistency Fix this by moving the mutex lock before the power state check, ensuring atomicity of the state check and modification.
