This became a build failure for the powerpc ppc64_allmodconfig build:

In file included from include/linux/i2c.h:13,
                 from arch/powerpc/platforms/pasemi/misc.c:14:
include/linux/acpi.h:682:31: error: 'struct acpi_device' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
  682 | acpi_dev_hid_uid_match(struct acpi_device *adev, const char *hid2, const char *uid2)
      |                               ^~~~~~~~~~~
cc1: all warnings being treated as errors

(and many more)

I have used the pm tree from next-20191014 for today.
