I certainly agree that it is better to use an already defined function
instead of reinventing the wheel.

But this new version causes an immediate reboot on my machine even with
the previously working speaker-test. If I interpret linux/log2.h correctly
the desired function should be order_base_2 instead of roundup_pow_of_two.
At least it works for me after that exchange.
