Subject: [PATCH 5.11 219/306] misc/pvpanic: Export module FDT device table

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

From: Shile Zhang <shile.zhang@...ux.alibaba.com>

commit 65527a51c66f4edfa28602643d7dd4fa366eb826 upstream.

Export the module FDT device table to ensure the FDT compatible strings
are listed in the module alias. This help the pvpanic driver can be
loaded on boot automatically not only the ACPI device, but also the FDT
device.
