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

Hi all,

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

Documentation/devicetree/kernel-api:56: /home/sfr/next/next/drivers/of/overlay.c:1184: WARNING: Inline emphasis start-string without end-string.

Introduced by commit

  24789c5ce5a3 ("of: overlay: detect cases where device tree may become corrupt")

Probably exposed by commit

  8c8239c2c1fb ("of: Add missing 'Return' section in kerneldoc comments")
