From 23c3e290fb9ce38cabc2822b47583fc8702411bf Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 20 Jan 2008 11:27:29 +0100 Subject: [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.
