I find this syntax odd, in addition to needing to check for NULL here as
Sean pointed out. Preferably just have it be the address of the
character pointer instead of making an anonymous array and then casting
that inline, i.e
.parent_names = &ref_clk_name,

This might be because of probe defer, which may be annoying to see this
failure many times.
