Subject: [PATCH] hmac.c: fix mismatching function prototype (#537)
The reported function raises a warning when compilers assert the flag
`-Warray-parameter=`, signaling that an array-type argument was promoted
to a pointer-type argument.
While in practice in most C implementations this is correct, fixing the
warning (and, in this case, indicating the maximum size for the array)
would represent a best-practice for finding out-of-bound accesses or
identifying wrongly-sized arrays passed in the function.
