commit 6210038aeaf49c395c2da57572246d93ec67f6d4 upstream.
Commit 104ff59af73a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI controller") enabled low power mode for the Tiger Lake AHIC adapter in the author system but created regressions for others. Revert this patch for now until a better solution is found to make this adapter eco-friendly.
