The patch below was submitted to be applied to the 4.14-stable tree.

I fail to see how this patch meets the stable kernel rules as found at Documentation/process/stable-kernel-rules.rst.

I could be totally wrong, and if so, please respond to stable@vger.kernel.org and let me know why this patch should be applied. Otherwise, it is now dropped from my patch queues, never to be seen again.

thanks,

greg k-h

On driver remove(), all objects created during probe() should be removed, but sysfs qemu_fw_cfg/rev file was left. Also reorder functions to match probe() error cleanup code.
