You're obviously right, thanks for taking the time to correct me.

Uhm, these don't want to render as hyperlinks. I guess it's because
these structs are not kernel-doc-annotated, nor are their .probe
methods. Probably not worth just doing that for the sake of this humble
patch.

Is it OK if I resend with just the basic syntax fix:
- ... bus-specific ->probe()
+ ... bus-specific probe()
?

Thanks,
