Would it be save to return at this point if the lock fails?

In other words, can I just add this? --> "if (ret) return ret;"

Done!

Same question. Would "if (ret) return ret;" be safe here?

Done!

I can also "return ret;" instead of "0".

What happens when a DEFINE_SHOW_ATTRIBUTE'd function returns non-zero? Is it ok?
Or do we want to always return "0" to print whatever we can?
