crypto: In crypto_add_alg(), 'exact' wants to be initialized to 0
We declare 'exact' without initializing it and then do: [...] if (strlen(p->cru_driver_name)) exact = 1; if (priority && !exact) return -EINVAL; [...] If the first 'if' is not true, then the second will test an uninitialized 'exact'. As far as I can tell, what we want is for 'exact' to be initialized to 0 (zero/false).
