    Subject[PATCH 4.4 73/76] ACPI / blacklist: Make Dell Latitude 3350 ethernet work
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

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

    [ Upstream commit 708f5dcc21ae9b35f395865fc154b0105baf4de4 ]

    The Dell Latitude 3350's ethernet card attempts to use a reserved
    IRQ (18), resulting in ACPI being unable to enable the ethernet.

    Adding it to acpi_rev_dmi_table[] helps to work around this problem.
