* gpu: nvgpu: Fix race in PMU state transitions.Deepak Goyal2017-10-25
| | | | | | | | | | | | | | | | | | | | | PMU response(intr callback for messages) can run faster than the kthread posting commands to PMU. This causes the PMU message callback to skip important pmu state change(which happens just after the PMU command is posted). Solution: State change should be triggered from only inside the intr callback. Other places can only update the pmu_state variable. This change also adds error check to print in case command post fails.
