Just checked them, interesting concept, guess we can think of something
also for the interval setting. That would effectively make all the
setting of the trigger set. Just my concern is that they may be too much
specific to netdev trigger and may be problematic for other kind of hw
control. (one main argument that was made for this feature was that some
stuff were too much specific and actually not that generic)

I deliberately made this API return a struct device, not a struct
net_device. That should keep it generic. The LED could then be
attached to an disk device, an mtd device, or a tty device, each of
which have an ledtrig-*.c file.
