So, what about setting this string to a default (e.g. '0' or 'generic' or
whatever). Then, userspace knows this is the unmodified upstream version of the
generic driver. If the generic driver is not sufficent for a user and he
patches it, he can simply patch the version string, too?

Or can we use the notifiers to set up an individual version? That could also be
the place to do special board-setup connected to the selected version.
