From: "Martin K. Petersen" <martin.peter...@oracle.com>

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

===============

commit 3b8d2676d15d6b2326757adb66b70a9cd6650373 upstream.

Queued trim only works for some users with MU05 firmware.  Revert to
blacklisting all firmware versions.

Introduced by commit d121f7d0cbb8 ("libata: Update queued trim blacklist
for M5x0 drives") which this effectively reverts, while retaining the
blacklisting of M550.

See

    https://bugzilla.kernel.org/show_bug.cgi?id=71371

for reports of trouble with MU05 firmware.
