Same as the report I already responded to:

https://lore.kernel.org/r/202306232330.luFAk63S-lkp@intel.com

...just a different config (powerpc-allmodconfig vs.
powerpc-randconfig-r025-20230622). Specifically this is the same
commit git hash and thus also points to v1 of the patch instead of the
newer v2.
