commit23c3e290fb9ce38cabc2822b47583fc8702411bf (patch)
parent[SCSI] libsas: abstract STP task status into a function (diff)
[SCSI] usbstorage: use last_sector_bug flag universally
This patch sets the last_sector_bug flag to 1 for all USB disks. This is needed to makes the cardreader on various HP multifunction printers work. Since the performance impact is negible we set this flag for all USB disks to avoid an unusual_devs.h nightmare.
