Short answer: Yeah, looks ok to me.

Longer answer: I mean, this way ghes_proc() *actually* propagates the
return value of ghes_read_estatus() and we don't do any processing if it
failed.

Which doesn't really tell me a whole lot about the actual processing,
i.e., what ghes_do_proc() did.

But ghes_do_proc() doesn't return anything and ghes_proc()'s retval is
used only in contexts where we're asking whether something got processed
or not.

And for that, that fix is adequate. So:
