ACPI / blacklist: add _REV quirks for Dell Precision 5520 and 3520
From: Alex Hung <alex.hung@canonical.com> [ Upstream commit 9523b9bf6dceef6b0215e90b2348cd646597f796 ] Precision 5520 and 3520 either hang at login and during suspend or reboot. It turns out that that adding them to acpi_rev_dmi_table[] helps to work around those issues. Signed-off-by: Alex Hung <alex.hung@canonical.com> [ rjw: Changelog ] Signed-off-by: Rafael J.
