The Dell Latitude 3350's ethernet card attempts to use a reserved IRQ (18), resulting in ACPI being unable to enable the ethernet. This patch forces a specific _REV (ACPI revision) value as a workaround to allow the Dell Latitude 3350's board to work correctly. The approach is similar to 18d78b64fddc11eb336f01e46ad3303a3f55d039 Signed-off-by: Michael Pobega <mpobega@neverware.com> --- drivers/acpi/blacklist.c | 12 ++++++++++++ 1 file changed, 12 insertions(+)
