* arm: dump: no need to check return value of debugfs_create functionsGreg Kroah-Hartman2019-06-031-6/+2Star
| | | | | | | | | | | | | 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.
