You really do not care, and obviously did not test this on a system with
CONFIG_DEBUG_FS disabled :)
Just make the call to debugfs, and move on, feed it into other debugfs
calls, all is good.
This function should just return 'void', no need to care about this at
all.

Why do you care about this "error"?
