5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuan Can yuancan@huawei.com
commit 734ac57e47b3bdd140a1119e2c4e8e6f8ef8b33d upstream.
The smsdvb_module_init() returns without checking the retval from smscore_register_hotplug(). If the smscore_register_hotplug() failed, the module failed to install, leaving the smsdvb_debugfs not unregistered.
