The first message will be emitted even without the changes if the bus is not
found. The second error will be emitted when check "/sys/bus/acpi" is not
found. We fail for all other buses by default except for NFIT as before and PAPR
tests are enabled only when NVDIMM_TEST_FAMILY is set to "PAPR".
All tests pass in my setup (x86_64 qemu guest) with the recent upstream kernel,
except for the the below warning from drivers/acpi/nfit/core.c:
