This reverts commit a979a6aa009f3c99689432e0cdb5402a4463fb88.
The reverted commit may cause VM freeze on arm64 platform. Because on arm64 platform, stop a consumer will suspend the VM, the VM will freeze without a start consumer

Please resubmit with the formal process of stable (stable-kernel-rules.rst).
sure, I will re-submit it to stable kernel once it is merged into Linus tree.
Thanks
I think it's better to resubmit (option 1), see how stable-kernel-rules.rst said:
""
:ref:`option_1` is **strongly** preferred, is the easiest and most common. :ref:`option_2` and :ref:`option_3` are more useful if the patch isn't deemed worthy at the time it is applied to a public git tree (for instance, because it deserves more regression testing first).

Thanks
Thanks
