  This can be const, and should thus be const.  (Also, resolves a compiler
warning.)

I think the patch is good, but it *so* does not apply for me...

Looked at the first two occurences, and the confusion is explained - this
change is already in "master" but not in 2.4

master/crypto.h

void init_key_ctx(struct key_ctx *ctx, const struct key *key,
                  const struct key_type *kt, int enc,
                  const char *prefix);

2.4/crypto.h

void init_key_ctx(struct key_ctx *ctx, struct key *key,
                  const struct key_type *kt, int enc,
                  const char *prefix);

I'm too lazy to trace which patch changed master, and did not get 
cherrypicked to 2.4 - but this is reasonable to apply to 2.4 (-only),
so I will :-) - ACK.

ACK, 2.4-only (already in master)

Your patch has been applied to the release/2.4 branch.
