libata: Blacklist queued trim for Crucial M500
Queued trim only works for some users with MU05 firmware. Revert to blacklisting all firmware versions. Introduced by commit d121f7d ("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. Signed-off-by: Martin K. Petersen <[email protected]> Cc: Alan Cox <[email protected]> Cc: Tejun Heo <[email protected]> Cc: [email protected] Signed-off-by: Linus Torvalds <[email protected]>
