Should this and other here not return error...? Indicating sdw is not available..? Silently ignoring may not be very helpful in debugging
Yeah I was a little unsure which way to go on that, in the end I opted for returning zero as it was more likely code would get optimised out. But I am happy to switch to returning an error, it would as you say making debugging misconfigurations easier. -ENOSYS seems kinda reasonable I think.
