Subject: [PATCH v3 1/4] leds: class: warn about name collisions earlier

Other warnings refer to the name after renaming, which is clearer when
that name is mentioned first.
It is also clearer where "ret" comes from.

While at it, also add the necessary newline to the message and fix the
parameter alignment.
