X-Git-Tag: v4.10-rc1~151^2~2^5
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=708f5dcc21ae9b35f395865fc154b0105baf4de4;p=linux.git

ACPI / blacklist: Make Dell Latitude 3350 ethernet work

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.
