3.6.11.9-rc1 stable review patch.
If anyone has any objections, please let me know.
------------------
From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx>
[ Upstream commit 7562523e84ddc742fe1f9db8bd76b01acca89f6b ]
If a device has the skip_vpd_pages flag set we should simply fail the
scsi_get_vpd_page() call.
