Subject[PATCH 3.18 21/52] usbip: Fix implicit fallthrough warning
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jonathan Dieter <jdieter@lesbg.com>

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.
