3.16.7-ckt16 -stable review patch.  If anyone has any objections, please let me 
know.

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

From: "Martin K. Petersen" <[email protected]>

commit 9051bd393cf25e76dfb45409792719a854661500 upstream.

A new Micron drive was just announced, once again recycling the first
part of the model string. Add an underscore to the M510/M550 pattern to
avoid picking up the new DC drive.
