Subject[PATCH v2] scsi: ufs: modify Tactive time setting conditions
Date
The Tactive time determine the waiting time before burst
at hibern8 exit and is determined by H/W at linkup state
However, in the case of samsung devices, guided host's Tactive time
+100us for stability.
If the HCI's Tactive time is equal or greater than the device,
+100us should be set.
