I'm not discussing the validity of _byname (Russell King is, but
that's not an argument I have a position of). What I'm saying is that
the kernel internal use of byname, and named resources in the DT are
different things which should be approached independently.

I'm not discussing the validity of _byname (Russell King is, but
that's not an argument I have a position of). What I'm saying is that
the kernel internal use of byname, and named resources in the DT are
different things which should be approached independently.
