Linus Torvalds 281e239698 ata fix for 6.14-final ...

- Fix a regression on ATI AHCI controllers, where certain Samsung
    drives fails to be detected on a warm boot when LPM is enabled.
 
    LPM on ATI AHCI works fine with other drives. Likewise, the
    Samsung drives works fine with LPM with other AHI controllers.
 
    Thus, just like the weirdo ATA_QUIRK_NO_NCQ_ON_ATI quirk, add a
    new ATA_QUIRK_NO_LPM_ON_ATI quirk to disable LPM only on ATI
    AHCI controllers.
