Subject: [PATCH 3.16 029/357] libata: widen Crucial M550 blacklist matching

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

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

From: Tejun Heo <tj@...nel.org>

commit 2a13772a144d2956a7fedd18685921d0a9b8b783 upstream.

Crucial M550 may cause data corruption on queued trims and is
blacklisted.  The pattern used for it fails to match 1TB one as the
capacity section will be four chars instead of three.  Widen the
pattern.
