How about: compr->ops = &soc_compr_ops; if (platform->driver->compr_ops && !platform->driver->compr_ops->copy) compr->ops->copy = NULL;
That way you set it to null for those who doent implement this and would called for drivers who implement this.
We'd need to take a copy of it in case we have a system with a mix of both styles.
For the same device?
Shouldnt you have two different device nodes and then use copy method on one which supports and memory-mapped for the one which doesn't?
