[PATCH 4.9 78/93] ACPI / blacklist: Make Dell Latitude 3350 ethernet work

From: Greg Kroah-Hartman
Date: Mon Mar 20 2017 - 14:22:19 EST


4.9-stable review patch. If anyone has any objections, please let me know.

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

From: Michael Pobega <mpobega@xxxxxxxxxxxxx>

[ 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.
