Hi Wei,
I just double-checked.
This issue has been fixed in a patch submitted by Dan Carpenter on 09th
Dec 2017 which I acknowledged on 11th Dec 2017 and which should be in
Richard's queue to be applied.
It should at some point show up in Linux-next.
Best Regards and once again, thanks for looking into it.
A.
