Hi Andy,

Thanks for your review.

I have remove some useless header file, refer to some others sensor
driver code(such as gc0a08/gc2145 and imx/ov sensor driver).
As these header files which mentioned above, are included by some other
header files, for example "container_of.h" is included by "media-
entity.h", while "media-entity.h" is inculded by "v4l2-subdev.h", so we
just need include "v4l2-subdev.h" in sensor driver code.
