+Subject: Documentation/media: uapi: Explicitly say there are no Invariant Sections
+Bug-Debian: https://bugs.debian.org/698668
+
+The GNU Free Documentation License allows for a work to specify
+Invariant Sections that are not allowed to be modified.  (Debian
+considers that this makes such works non-free.)
+
+The Linux Media Infrastructure userspace API documentation does not
+specify any such sections, but it also doesn't say there are none (as
+is recommended by the license text).  Make it explicit that there are
+none.
