[PATCH v2] scsi/ufs: Fix evaluation of UTP task completion code

From: Venkatraman S
Date: Thu Apr 19 2012 - 02:10:27 EST


While interpreting the result of UTP task completion status,
by using boolean &&, the evaluation would fail when the
UPIU_TASK_MANAGEMENT_FUNC_SUCCEEDED was received.

Either UPIU_TASK_MANAGEMENT_FUNC_COMPL or
UPIU_TASK_MANAGEMENT_FUNC_SUCCEEDED should be
considered as a success result.
