+From 273b9fb93e4b2cfff7aeff8ea559219c2755ee95 Mon Sep 17 00:00:00 2001
+From: Garrett <g@floft.net>
+Date: Thu, 2 Jul 2015 19:32:04 -0500
+Subject: [PATCH 151/171] bcm2835 camera planar/packed stride length
+
+Added a field to the mmal_fmt struct used to compute the bytes per line
+when using a particular format. This results in the correct stride being
+calculated even when the format is planar.
