+Subject: [PATCH] include/Makefile.am: don't install lightning.h twice
+
+Commit 17164ed32d8f3530153b9cad67a4399c65f24512 added lightning.h to
+nodist_include_HEADERS without removing it from include_HEADERS
+
+This raises the following error on one of the buildroot autobuilders:
+/usr/bin/install -c -m 644 lightning.h '/home/test/autobuild/run/instance-3/output-1/target/usr/include'
+/usr/bin/install -c -m 644 lightning.h '/home/test/autobuild/run/instance-3/output-1/target/usr/include'
+/usr/bin/install: cannot create regular file `/home/test/autobuild/run/instance-3/output-1/target/usr/include/lightning.h': File exists
+
+Fix this by removing lightning.h from include_HEADERS
