2282e125a4 leds: triggers: let struct led_trigger::activate() return an error code
Given that activating a trigger can fail, let the callback return an
indication. This prevents to have a trigger active according to the
"trigger" sysfs attribute but not functional.

All users are changed accordingly to return 0 for now. There is no intended
change in behaviour.

e64c97b53b Bluetooth: Add combined LED trigger for controller power
Instead of just having a LED trigger for power on a specific controller,
this adds the LED trigger "bluetooth-power" that combines the power
states of all controllers into a single trigger. This simplifies the
trigger selection and also supports multiple controllers per host
system via a single LED.

Add support for LED triggers to the Bluetooth subsystem and add kernel

For now one trigger for indicating "HCI is powered up" is supported.
