Subject: libata: Do not blacklist Micron M500DC
From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx>
commit 243918be6393f643e513a26e7882e6ae06ff7717 upstream.
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.
