Thanks, I saw one comment given in the V1 patch is not addressed in V2.
Please refer to the inline comment below:

For the above debug message, could you help to keep the origin format that will display the UFS controller index?
  DEBUG ((DEBUG_INFO, "Ufs %d Lun %d is enabled\n", Controller, Index));
