+Subject: [PATCH] kdbus: fix unused %docs make-targets
+
+The top-level Makefile re-routes all %docs targets to the Documentation
+makefiles. The DocBook makefile supports a lot more targets than the kdbus
+makefile, and it seems unreasonable to expect that both will always be in
+sync.
+
+Therefore, add a fallback no-op target %docs: which is used for all
+unspecified %docs targets.
+
+We will, from time to time, add further %docs targets that make sense
+(like installdocs). But there is definitely no time pressure on those.
+However, we really should add this fallback now, as otherwise "make" will
+print errors due to unknown targets.
