From a7c3abc971eb4e7771697a70f8b6ca42bc2b1db0 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Subject: [PATCH] staging/bcm2835-codec: Fix support for levels 4.1 and
4.2
The driver said it supported H264 levels 4.1 and 4.2, but
was missing the V4L2 to MMAL mappings.
Add in those mappings.
