Subject: [PATCH 4.4 009/268] libata: blacklist Micron 500IT SSD with MU01 firmware

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

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

From: Sudip Mukherjee <sudipm.mukherjee@...il.com>

commit 136d769e0b3475d71350aa3648a116a6ee7a8f6c upstream.

While whitelisting Micron M500DC drives, the tweaked blacklist entry
enabled queued TRIM from M500IT variants also. But these do not support
queued TRIM. And while using those SSDs with the latest kernel we have
seen errors and even the partition table getting corrupted.

Some part from the dmesg:
[    6.727384] ata1.00: ATA-9: Micron_M500IT_MTFDDAK060MBD, MU01, max UDMA/133

and then for the error:

[  121.204559] print_req_error: I/O error, dev sda, sector 272512

After few reboots with these errors, and the SSD is corrupted.
After blacklisting it, the errors are not seen and the SSD does not get
corrupted any more.
