Hi Daniel, Henrik,

I understand that I am a bit late to the party :) but I do not agree
with this change. Failure to create attributes is not sometihng that
user could cause (at least not easily) and thus would not be a setup
issue but something more severe. I believe we should fail loading the
driver so sysfs attribute breakage will be noticed as soon as possible,
instead of discovering it much much later in the process.

So I think we should revert this one.

Thanks.
