Hey again,

Actually... It looks like the issue is that in this file:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/crypto/internal/blake2s.h

this line

typedef void (*blake2s_compress_t)(struct blake2s_state *state,
const u8 *block, size_t nblocks, u32 inc);

should become

typedef void (*blake2s_compress_t)(struct blake2s_state *state,
const u8 *block, size_t nblocks, const u32 inc);

Does making that change fix things for you?

Thanks,
Jason
