From 1dbe31a80537e398865442562fd21d4cb3fa6dcc Mon Sep 17 00:00:00 2001

Subject: [PATCH] staging:vc04_services: bcm2835-camera: Request
headers with I-frame
V4L2 wishes to have the codec header bytes in the same buffer as the
first encoded frame, so it does become 1-in 1-out for encoding.
The firmware now has an option to do this, so enable it.
