If anyone has any objections, please let me know. ------------------ From: Michael Pobega [ 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.
