Subject: linux-next: build failure after merge of the pm tree

Hi all,

After merging the pm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

In file included from <command-line>:
include/linux/intel_rapl.h:116:19: error: field 'pcap_rapl_online' has incomplete type
  enum cpuhp_state pcap_rapl_online;
                   ^~~~~~~~~~~~~~~~

Caused by commit

  7ebf8eff63b4 ("intel_rapl: introduce struct rapl_if_private")

This was detected by the new test that attempts to build each include
file standalone.

I have added the following fix patch for today:
