4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonathan Dieter <jdieter@xxxxxxxxx>
commit cfd6ed4537a9e938fa76facecd4b9cd65b6d1563 upstream.
GCC 7 now warns when switch statements fall through implicitly, and with
-Werror enabled in configure.ac, that makes these tools unbuildable.
We fix this by notifying the compiler that this particular case statement
is meant to fall through.
