Any Coverity wizards?

[Hal Murray]

I expect the comment on the previous line to tell Coverity to not complain 
about this case.

Is there a typo or such that I'm missing?

149        /* coverity[checked_return] */
  CID 462307 (#1 of 1): Unchecked return value (CHECKED_RETURN)
  15. check_return: Calling CMAC_Update without checking return value (as is 
done elsewhere 5 out of 6 times).
150        CMAC_Update(cmac_ctx, data, (unsigned int)datalen);
