In the Linux kernel, the following vulnerability has been resolved:
misc: ocxl: fix possible double free in ocxl_file_register_afu
info_release() will be called in device_unregister() when info->dev's reference count is 0. So there is no need to call ocxl_afu_put() and kfree() again.
Fix this by adding free_minor() and return to err_unregister error path.
