linux-next: build warning after merge of the powerpc tree

Hi all,

After merging the powerpc tree, today's linux-next build (htmldocs)
produced this warning:

Documentation/ABI/testing/sysfs-bus-event_source-devices-vpa-pmu:2: ERROR: Unexpected indentation.

Introduced by commit

  4ae0b32ecee7 ("docs: ABI: sysfs-bus-event_source-devices-vpa-pmu: Document sysfs event format entries for vpa_pmu")
