Jason A. Donenfeld 714def4497 riscv: use fallback for random_get_entropy() instead of zero ... commit 6d01238623faa9425f820353d2066baf6c9dc872 upstream. In the event that random_get_entropy() can't access a cycle counter or similar, falling back to returning 0 is really not the best we can do. Instead, at least calling random_get_entropy_fallback() would be preferable, because that always needs to return _something_, even falling back to jiffies eventually. It's not as though random_get_entropy_fallback() is super high precision or guaranteed to be entropic, but basically anything that's not zero all the time is better than returning zero all the time.
