linux-next: build warning after merge of the v4l-dvb tree

Hi all,

After merging the v4l-dvb tree, today's linux-next build (htmldocs)
produced this warning:

Documentation/driver-api/media/v4l2-subdev.rst:125: WARNING: Inline interpreted text or phrase reference start-string without end-string.

Introduced by commit

  25c8d9a7689e ("media: Documentation: v4l: Document that link_validate op is valid for sink only")
