Do we want to get rid of it, or do we want to have a string version per
DSA implementation? (old vs. new bindings).

I don't like the actual way to distinguish between the two (grep'ing
dmesg as Florian shown). Maybe a pr_info in dsa2.c would be enough to
inform about DSA "v2". What do you guys prefer?

Thanks,

        Vivien
