I think his actually needs to be merged via netdev.  e0256648c831
("net: dsa: qca8k: implement hw_control ops") is in net-next/main.  I
don't see it in leds/master, leds/for-leds-next. Also, git blame shows
mode was added by 0316cc5629d1 ("leds: trigger: netdev: init mode if
hw control already active") which also appears only to be in
net-next/main.

A lot of these LED patches were merged via netdev because they are
cross subsystem.
