From 96402de65afcd9d7f12e04bf8a14d5a321aca4af Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 19 Sep 2018 20:14:51 +0200 Subject: [PATCH] platform/x86: intel_int0002_vgpio: Enable the driver on Bay Trail platforms The intel_int0002_vgpio driver was added to avoid an IRQ 9 storm on Cherry Trail platforms. When originally merged the CPU ID for Bay Trail SoCs was commented out of the list of valid CPU IDs because we did not have any reports of the IRQ storm on Bay Trail platforms. We now have a report of the IRQ 9 storm on the Bay Trail based Thinkpad Tablet 10 which is fixed by enabling this driver, so lets enable it on Bay Trail too. I've tested various other Bay Trail device with this driver enabled without adverse side-effects.
