CVE-2022-50244

CVE-2022-50244 affects the Linux kernel code path in cxl_pci_init_afu|adapter() where a failed device_register() leaves a not-added device and leads to a potential null pointer dereference if device_unregister() is called in the error path. The fix splits unregister logic into device_del() and pu...
