New sysfs files need documentation.
Plus, this probably should use this interface, not custom one:
Documentation/ABI/testing/sysfs-class-led-trigger-pattern:What: /sys/class/leds/<led>/hw_pattern
It might be better to submit driver without pattern support, then
re-add it when driver is merged.
Best regards,
Pavel
