As was in the original code, please move this after -

if (!smu_is_dpm_running(smu))
                dev_info(adev->dev, "dpm has been disabled\n");

This point completes all the diagnostic messages related to DPM feature
enable stage. That helps to check if any issue happened before fetching
tables from firmware.

Thanks,
Lijo
