Hi! > These patch series add the LED_BRIGHTNESS_FAST flag support for > ledtrig-transient to use hrtimer so that platforms with high-resolution timer > support can have better accuracy in the trigger duration timing.

LEDs do not need extra overhead, and vibrator control should not go through LED subsystem. Input subsystem includes support for vibrations and force feedback. Please use that instead.
