Before this patch, USB storage devices disabled VPD check by always setting skip_vpd_check.
The first patch add a new entry to scsi_static_device_list related to SanDisk Cruzer Blade, which have VPD, adding BLIST_TRY_VPD_PAGES flag, which implies try_vpd_pages. The second patch check try_vpd_pages, and only set skip_vpd_pages if try_vpd_pages is not set. This patches along the wwid one [1], makes SanDisk Cruzer Blade device to present correctly wwid, vpd_pg80 and vpd_pg83 in sysfs, and let the window open to support another USB storage devices to support and present VPD.
