+Subject: [PATCH] Fix mjpg-streamer to work with kernel 3.18
+
+I didn't create this fix, it was originally posted to http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=97983&p=681259.  @koosvriezen tried to create a pull request #3 but made kind of a hash of it, so this is the same fix only a proper pull request.
