Subject: [PATCH 3.13 078/149] libata: disable queued TRIM for Crucial M500 mSATA SSDs

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

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

From: Marios Andreopoulos <opensource@...marios.com>

commit 2564338b13e6e132ee224edb63e1e872adf431f4 upstream.

Queued TRIM commands cause problems and silent file system corruption
on Crucial M500 SSDs. This patch disables them for the mSATA model of
the drive.
