From 9523b9bf6dceef6b0215e90b2348cd646597f796 Mon Sep 17 00:00:00 2001 From: Alex Hung Date: Fri, 28 Oct 2016 11:54:04 -0700 Subject: ACPI / blacklist: add _REV quirks for Dell Precision 5520 and 3520 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 [ rjw: Changelog ] Signed-off-by: Rafael J.
