    Subject[PATCH 5.12 183/242] mmc: sdhci-acpi: Disable write protect detection on Toshiba Encore 2 WT8-B
    Date
    From: Hans de Goede <hdegoede@redhat.com>

    commit 94ee6782e045645abd9180ab9369b01293d862bd upstream.

    On the Toshiba Encore 2 WT8-B the microSD slot always reports the card
    being write-protected even though microSD cards do not have a write-protect
    switch at all.

    Add a new DMI_QUIRK_SD_NO_WRITE_PROTECT quirk entry to sdhci-acpi.c's
    DMI quirk table for this.
