[PATCH v2] ata: libata-core: Disable LPM on ST1000DM010-2EP102

[Maximilian Pezzullo via B4 Relay]

From: Maximilian Pezzullo <maximilianpezzullo@gmail.com>

According to a user report, the ST1000DM010-2EP102 has problems with LPM,
causing random system freezes since kernel 6.15. The drive belongs to the
same BarraCuda family as the ST2000DM008-2FR102 which has the same issue.

Beside removing the copilot related tag, no changes here. Still looks good.

Niklas,

This I think needs a CC-stable. Can you add that when applying ?

CC-stable added.

Also dropped reference to 6.15, since if this drive has LPM problems the
fix should be backported as far back as possible, not only to 6.15.

We've had mobile platforms with LPM support for a very long time.
We enabled LPM for non-mobile platforms in v6.9, so to be pragmatic,
that is the Fixes tag I chose, even though in reality mobile platforms
would have seen issues with this drive even before then:
