6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sakari Ailus sakari.ailus@linux.intel.com
commit 9537a8425a7a0222999d5839a0b394b1e8834b4a upstream.
The notifier_entry of a notifier is not re-initialised after unregistering the notifier. This leads to dangling pointers being left there so use list_del_init() to return the notifier_entry an empty list.
