    Subject[PATCH AUTOSEL 4.18 071/126] libata: Apply NOLPM quirk for SAMSUNG MZ7TD256HAFV-000L9
    Date
    From: Diego Viola <diego.viola@gmail.com>

    [ Upstream commit a435ab4f80f983c53b4ca4f8c12b3ddd3ca17670 ]

    med_power_with_dipm causes my T450 to freeze with a SAMSUNG
    MZ7TD256HAFV-000L9 SSD (firmware DXT02L5Q).

    Switching the LPM to max_performance fixes this issue.
