The other NULL assignment isn't useful either.  Also If
"entropy_collector" is NULL then we would oops calling
kzfree(entropy_collector->mem);
       ^^^^^^^^^^^^^^^^^^^^^^
Dereference.

I don't understand the patch that you sent.  We shouldn't be introducing
jent_zalloc() or jent_zfree().  Why are you adding abstractions there?
Quite bad ones as well.
