Core code already clears reserved fields of struct
v4l2_pix_format_mplane, check: 4e1e0eb0e074 ("media: v4l2-ioctl: Zero
v4l2_plane_pix_format reserved fields").

Hi Ricardo,

Thanks a lot for doing this media-wide cleanup.

Aside from a silly typo here in the commit title, s/sum4i-csi/sun4i-csi,
all the patches seem fine.

Thanks,
Ezequiel
