Subject: libata: Blacklist queued trim for Crucial M500
From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx>
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.
