libata: whitelist all SAMSUNG MZ7KM* solid-state disks
These devices support read zero after trim (RZAT), as they advertise to the OS. However, the OS doesn't believe the SSDs unless they are explicitly whitelisted. Acked-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Juha-Matti Tilli <juha-matti.tilli@iki.fi> Signed-off-by: Jens Axboe <axboe@kernel.dk>
