media-ctl: fix build with old kernel headers
Add a patch to fix the recurrent media-ctl build problems with toolchains based on relatively old (< 2.6.39) kernel headers. Finally fixes: http://autobuild.buildroot.org/results/54a/54afc80d4b58a4064a49226bcd4a28f32e3cf814/build-end.log Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Tested-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

+Subject: [PATCH] Add kernel headers for compatibility with old toolchains
+
+The media controller mechanism is relatively new in the Linux kernel,
+and therefore all toolchains don't yet have the necessary
+headers. This patch makes sure that media-ctl provides such headers,
+as was already the case with v4l2-common.h, v4l2-subdev.h and
+videodev2.h.
