[PATCH V4 4/4] [SCSI] ufs: Correct the expected data transfer size

From: Vinayak Holikatti
Date: Wed Oct 17 2012 - 07:56:03 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
