Subject: libata: Enable queued TRIM for Samsung SSD 860
From: Ju Hyung Park <qkrwngud825@gmail.com>
commit ca6bfcb2f6d9deab3924bf901e73622a94900473 upstream.
Samsung explicitly states that queued TRIM is supported for Linux with
860 PRO and 860 EVO.
Make the previous blacklist to cover only 840 and 850 series.
