I think this is not sufficient, crypto_alg_match() will now return the first
algorithm in crypto_alg_list that matches cra_name. We would need to extend
crypto_alg_match() to return the algorithm with the highest priority in that
case.

It doesn't really matter because all implementations must provide
exactly the same set of parameters for a given algorithm so it's
good enough for what Stephan wants to do.

Ok, I see.

But yes an interface to grab the highest priority algorithm would
be useful too so patches are welcome :)

Should be not too hard to return the highest priority algorithm
instead of the first match with the existing interface, I'll see
what I can do.
