This looks the same as
https://lore.kernel.org/oe-kbuild-all/202407032306.gi9nZsBi-lkp@xxxxxxxxx/
and both should be fixed by
https://lore.kernel.org/all/20240703221520.4108464-1-surenb@xxxxxxxxxx/
which I believe is in mm-hotfixes-stable branch:
https://lore.kernel.org/all/20240709224150.B4711C3277B@xxxxxxxxxxxxxxx/
