Subject: [ 01/60] SCSI: Dont attempt to send extended INQUIRY command if skip_vpd_pages is set

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Martin K. Petersen" <martin.petersen@...cle.com>

commit 7562523e84ddc742fe1f9db8bd76b01acca89f6b upstream.

If a device has the skip_vpd_pages flag set we should simply fail the
scsi_get_vpd_page() call.
