The use of strncpy() in the set_led_id() was incorrect. The len variable should use 'min(sizeof(buf2) - 1, count)' expression.

Use strscpy() function to simplify things and handle the error gracefully.

Let's use the normal Link tag instead of BugLink. The former is preferred.

Also, it'd be great if you can put the Fixes tag, too.

Done. Sent v3.
