Why are you using CRYPTO_RNG_DEFAULT when you are using get_random_bytes
here?

Errm ... do I?
Seems that my crypto ignorance is showing here; 'get_random_bytes()' is
the usual function we're using for drivers; if there is another way for
crypto please enlighten me.

Apologies, I was looking at CONFIG_RNG where you set CRYPTO_RNG_DEFAULT. 
Please ignore my comment here.
