Subject: [PATCH AUTOSEL 5.15 1/6] ACPI: button: Add lid disable DMI quirk for Nextbook Ares 8A

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit 4fd5556608bfa9c2bf276fc115ef04288331aded ]

The LID0 device on the Nextbook Ares 8A tablet always reports lid
closed causing userspace to suspend the device as soon as booting
is complete.

Add a DMI quirk to disable the broken lid functionality.
