Hi Alan,

Thank you for your reply. As for your comment regarding the LED feature flag, the driver can provide a flag parameter for LED
feature so that users will be able to set this LED feature at loading the driver, and by default, this flag is set false (LED
feature is disabled). Could you let me know if this is what exactly matches your comment?

Regards,
Donald

I would just enable this. Nobody is going to change it in their source code.

Same comment as before about leds and flags to indicate features.

All these if cases should be a feature flag of some kind
