This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
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.
