media: v4l: async: Properly re-initialise notifier entry in unregister
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.
Fixes: b8ec754ae4c5 ("media: v4l: async: Set v4l2_device and subdev in async notifier init")
Cc: <stable@vger.kernel.org> # for 6.6 and later
