[SCSI] sd: don't fail if the device doesn't recognize SYNCHRONIZE CACHE Evidently some wacky USB-ATA bridges don't recognize the SYNCHRONIZE CACHE command, as shown in this email thread: http://marc.info/?t=138978356200002&r=1&w=2 The fact that we can't tell them to drain their caches shouldn't prevent the system from going into suspend. Therefore sd_sync_cache() shouldn't return an error if the device replies with an Invalid Command ASC.
