From 0c2f287ea670acbf9d4ed68efd55b5f2b76b50ca Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>

Subject: [PATCH 1/2] platform/x86: asus-nb-wmi: Allow configuring
SW_TABLET_MODE method with a module option
Unfortunately we have been unable to find a reliable way to detect if
and how SW_TABLET_MODE reporting is supported, so we are relying on
DMI quirks for this.
Add a module-option to specify the SW_TABLET_MODE method so that this can
be easily tested without needing to rebuild the kernel.
