libata: Do not blacklist Micron M500DC
Queued TRIM got disabled on Micron M500DC drives thanks to the "Micron_M500*" pattern we had in place to accommodate the previous generation of this drive family. Tweak the blacklist entry slightly so we only disable queued TRIM for the non-DC variants of M500 drives. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Cc: stable@vger.kernel.org Signed-off-by: Tejun Heo <tj@kernel.org>
