scsi: introduce a quirk for false cache reporting
Some SATA to USB bridges fail to cooperate with some drives resulting in no cache being present being reported to the host. That causes the host to skip sending a command to synchronize caches. That causes data loss when the drive is powered down. Signed-off-by: Oliver Neukum <oneukum@suse.com> Reviewed-by: Martin K.
