I confirm the structure disappeared in between kernel 3.10 and 3.11 (see
include/uapi/linux/videodev2.h). Commit b71c9980 explains that this
structure
and the associated ioctl were deprecated and therefore removed.
In other words Freescale shouldn't use that structure. I'll offer another
patch
that replaces chip_ident by chip_info.

Thanks,
Gary
