    Subject[PATCH 4.15 041/105] libata: Make Crucial BX100 500GB LPM quirk apply to all firmware versions
    Date
    4.15-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Hans de Goede <hdegoede@redhat.com>

    commit 3bf7b5d6d017c27e0d3b160aafb35a8e7cfeda1f upstream.

    Commit b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB
    drive"), introduced a ATA_HORKAGE_NOLPM quirk for Crucial BX100 500GB SSDs
    but limited this to the MU02 firmware version, according to:
    http://www.crucial.com/usa/en/support-ssd-firmware

    MU02 is the last version, so there are no newer possibly fixed versions
    and if the MU02 version has broken LPM then the MU01 almost certainly
    also has broken LPM, so this commit changes the quirk to apply to all
    firmware versions.

    Fixes: b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB...")
