Unnecessary initialisation.

here too. This and 'int i = 0;' happens in many functions.

Maybe use if (err != 0) { kfree(opt); return NULL; } because goto out is
only used once?

int rc is unnecessary because the function always returns 0. This
happens in many places.

The SI multiplier is 'k', not 'K'.
