4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Guillermo A. Amaral" <g@maral.me>

commit 7a7184b01aa9deb86df661c6f7cbcf69a95b728c upstream.

The Crucial M500 is known to have issues with queued TRIM commands, the
factory recertified SSDs use a different model number naming convention
which causes them to get ignored by the blacklist.

The new naming convention boils down to: s/Crucial_/FC/
