    commit d4b1bba76171cb783e32441b28462fe841073ed8 upstream.
    Most of the hid sensor field size is reported in report_size field
    in the report descriptor. For rotation fusion sensor the quaternion
    data is 16 byte field, the report size was set to 4 and report
    count field is set to 4. So the total size is 16 bytes. But the current
    driver has a bug and not taking account for report count field. This
    causes user space to see only 4 bytes of data sent via IIO interface.
    The number of bytes in a field needs to take account of report_count
    field. Need to multiply report_size and report_count to get total
    number of bytes.
