Please take a look at for example:

https://lkml.iu.edu/hypermail/linux/kernel/1901.2/06005.html
https://lkml.iu.edu/hypermail/linux/kernel/1901.2/06006.html
https://lkml.iu.edu/hypermail/linux/kernel/1901.2/05993.html

This is the author of debugfs remove exactly the sort of code you are
adding.

Please teach the Zeal Bot that such code is wrong, and you should be
submitting patches to actually remove testing the return values for
anything which starts with debugfs_
