[ Upstream commit 71712cf519faeed529549a79559c06c7fc250a15 ]
The ionic_setup_one() creates a debugfs entry for ionic upon successful execution. However, the ionic_probe() does not release the dentry before returning, resulting in a memory leak.
To fix this bug, we add the ionic_debugfs_del_dev() to release the resources in a timely manner before returning.
