The V4L2_SEL_TGT_NATIVE_SIZE target is used to denote e.g. the size of a
sensor's pixel array.

The edid array is copied to kernelspace by the v4l2 core, so drivers
shouldn't see the __user annotation. This conforms to other structs like
v4l2_ext_controls where the data pointed to is copied to from user to
kernelspace.

As reported by Linus, make headers_check is reporting:
usr/include/linux/v4l2-common.h:72: found __[us]{8,16,32,64} type without #include <linux/types.h>
which seems to have come in through commits 777f4f85b75f1 and
254a47770163f.
That happens because struct v4l2_edid should be visible by both
subdev and V4L2 APIs. So, it was moved to v4l2-common.h.
As Linus pointed, the proper fix is to just add an include for
linux/types.h at v4l2-common.h.

Struct v4l2_subdev_edid and the VIDIOC_SUBDEV_G/S_EDID ioctls were
specific for subdevices, but for hardware with a simple video pipeline
you do not need/want to create subdevice nodes to just get/set the EDID.
Move the v4l2_subdev_edid struct to v4l2-common.h and rename as
v4l2_edid. Add the same ioctls to videodev2.h as well, thus allowing
this API to be used with both video nodes and v4l-subdev nodes.
