Subject: [PATCH 2/3] scsi: ufs: Fix sending unsupported SCSI command
Date: Tue,  1 Jul 2014 12:22:38 +0300	[thread overview]
Message-ID: <1404206559-21445-3-git-send-email-draviv@codeaurora.org> (raw)
In-Reply-To: <1404206559-21445-1-git-send-email-draviv@codeaurora.org>

From: Sujit Reddy Thumma <sthumma@codeaurora.org>

UFS 1.1 specification does not support MAINTENANCE IN(0xA3) SCSI
command and hence it doesn't support REPORT SUPPORTED OPERATION CODES
as well.
