This fixes the following warning:

In file included from drivers/media/video/v4l2-subdev.c:29:
include/media/v4l2-ctrls.h:501: warning: 'struct file' declared inside
parameter list
include/media/v4l2-ctrls.h:501: warning: its scope is only this
definition or declaration, which is probably not what you want
