Subject: [PATCH 3.16.y-ckt 081/118] libata: Do not blacklist M510DC

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

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

From: "Martin K. Petersen" <martin.petersen@...cle.com>

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.
