-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.
