mm/memory_hotplug: use pgprot_val to get value of pgprot
$ git grep "pgprot\.pgprot"
arch/ia64/mm/init.c: if (WARN_ON_ONCE(params->pgprot.pgprot !=
PAGE_KERNEL.pgprot))
arch/s390/mm/init.c: if (WARN_ON_ONCE(params->pgprot.pgprot !=

mm/memory_hotplug.c: if (WARN_ON_ONCE(!params->pgprot.pgprot))
You can change other's codes too.
