    Subject[PATCH 4.4 241/342] ACPI / video: Add disable_backlight_sysfs_if quirk for the Toshiba Portege R700
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

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

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

    commit de588b8ff057d4de0751f337b930f90ca522bab2 upstream.

    The Toshiba Portege R700 needs disable_backlight_sysfs_if=1, just like
    the Toshiba Portege R830. Add a quirk for this.
