[PATCH v2 0/6] misc LPM related fixes

[Niklas Cassel <cassel@kernel.org>]

Hello there,

we had a recent bug report on the mailing list related to LPM, which made
me review the LPM related code.

While doing so, I found some issues. This series fixes those issues.

The most serious issue is that ATA_QUIRK_NOLPM was not getting applied for
ATAPI devices and that we read the per port area for unimplemented ports,
even though the AHCI specification explicitly forbids this.


Kind regards,
Niklas


Changes since v1:
-Fixed typos in commit messages
-Split early return patch into two, so that they only have a single
 Fixes-tag each.
-Reordered patches to make it easier to only apply the important ones
 for the current v6.19 kernel.
