4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Pobega <mpob...@neverware.com>
[ 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.
