Cover letter [PATCH v2 0/1] ata: ahci: Revert "ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list"
From: Jason Nader <[email protected]>
Changes - updated commit message as per the kind guidance from Niklas.
I was not sure whether to cc stable, but if so it would allow affected users to start to be able to use kernel versions > 6.6.10.
Below are logs including the extra logging asked for by Niklas.

Note I also tested a patch that changes the Alder Lake entry from board_ahci_pcs_quirk to board_ahci, and that booted fine as well. However since it is not clear whether it is Alder Lake-S or Alder Lake-P that was meant to be added to the list in the first place, I have not committed that patch.
