yes

I've been sweeping the kernel tree to remove this anti-pattern. The debugfs core will print an error if you got something wrong, just call the function and move on, you NEVER need to check the return value of a debugfs call.
Yes, sorry to make your blood pressure go up... I missed this one in the cleanups yesterday. will fix.
