6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wentao Liang <Wentao_liang_g@xxxxxxx>
[ 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.
Fixes: 0de38d9f1dba ("ionic: extract common bits from ionic_probe")
