From 44d7b4f2225a120a4ecaa3b0528c9fc9ce6bfafb Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Subject: [PATCH] staging/vc04_services: Add additional unpacked raw
formats
Support has been added for the unpacked (16bpp) versions of
the MIPI raw 10, 12, and 14 formats, so add the 4CCs for them.
