[PATCH 14/44] drivers/char/hw_random: use min3() instead of nested min_t()

[david . laight . linux]

From: David Laight <david.laight.linux@xxxxxxxxx>

min_t(u16, a, b) is likely to discard significant bits.
Replace:
	min_t(u16, min_t(u16, default_quality, 1024), rng->quality ?: 1024);
with:
	min3(default_quality, 1024, rng->quality ?: 1024);
