Thanks John for this patch, and thanks Moritz for taking care of this.
Sorry for late response, one thing here we may need to be careful is
a recent bug fixing patch, that fixing patch has been merged by Greg
in char-misc-next tree, and may have some conflict with this one.

https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/commit/?h=char-misc-next&id=c9d7e3da1f3c4cf5dddfc5d7ce4d76d013aba1cc
fpga: dfl: afu: Corrected error handling levels

I guess we need to rebase this patch on top of it?
Moritz, do you have any suggestion?

Thanks
Hao
