CVE-2021-47143 net/smc: remove device from smcd_dev_list after failed device_add()

In the Linux kernel, the following vulnerability has been resolved: net/smc: remove device from smcddevlist after failed deviceadd If the deviceadd for a smcddev fails, there's no cleanup step that rolls back the earlier listadd. The device subsequently gets freed, and we end up with a corrupted...
