X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b8687d83b34cf372b943c5639d8960703aeb2b8e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ACPI / blacklist: Make Dell Latitude 3350 ethernet work

From: Michael Pobega <mpobega@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.
