[PATCH V3 4/4] [SCSI] ufs: Correct the expected data transfer size

From: Vinayak Holikatti
Date: Thu Jul 26 2012 - 04:45:08 EST


This patch corrects the expected data transfer size of the
command UPIU. The current implementation of cmd->transfersize
is wrong as it probably equal to sector size. With this
implementation the transfer size is updated correctly
