I don't understand. Why not just set the priority depending on
IS_ENABLED(CONFIG_ARM)? That way it's strictly better than the
Kconfig patch:

1) If the driver is indeed slower then you'd have achieved the same
result of preferring the non-driver algorithm.

2) If the driver ends up being faster then at least the admin can
adjust the priorities.

Or perhaps your Kconfig option should set the priority.

Cheers,
