From 56c28e7983a8c877e99de0152ce3f7f5eea98963 Mon Sep 17 00:00:00 2001 From: Michael Pobega Date: Fri, 17 Mar 2017 00:48:32 +0000 Subject: [PATCH] ACPI / blacklist: Make Dell Latitude 3350 ethernet work [ 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. Signed-off-by: Michael Pobega [ rjw: Changelog ] Signed-off-by: Rafael J.
