/*
* Android has a habit of trying to set the vibrator trigger to "transient",
* which destroys our own "activate", "duration", and "state" attributes.
* Remove the "trigger" attribute provided by leds_class so that no one can
* change the trigger of the vibrator LED device.
*
* Luckily, `sysfs_remove_file` only uses the `name` field, so we can use a
* compound literal instead of having to find the proper attribute struct
