When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

This makes sense.

Tomi, will you take this patch in your tree ?
Yes, I'll pick this up. I presume debugfs_create_file() will give a warning print if it fails to create the file, instead of being silent.
Yes it does, please see 43e23b6c0b01 ("debugfs: log errors when something goes wrong") and c33d442328f5 ("debugfs: make error message a bit more verbose") for the details if you are curious.
Those warnings have already found at least one user of debugfs that was doing things wrong and no one had noticed before.
thanks,
greg k-h
