So if the return value is to be used as a "real" dentry, it needs to be checked if it is an error before dereferencing it. This is now happening because of ff9fb72bc077 ("debugfs: return error values, not NULL"). If multiple iwlwifi devices are in the system, this can cause problems when the driver attempts to create the main debugfs directory again. Later on in the code we fail horribly by trying to dereference a pointer that is an error value.
