linux-next: build warning after merge of the Linus' tree

Hi all,

Building Linus' tree today linux-next (x86_64_allmodconfig)
produced quite a few of these warnings:

include/media/soc_camera.h: In function 'soc_camera_i2c_to_vdev':
include/media/soc_camera.h:257:34: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

This was introduced by commit 2f0babb7e432 ("[media] V4L: soc-camera:
make (almost) all client drivers re-usable outside of the framework").

This warning is caused by the "grp_id" member of "struct v4l2_subdev" -
which is a u32 - being cast to a pointer. That pointer is dereferenced,
so I have no idea how that is supposed to work on any 64 bit platform.
