Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/250800658bf3db32e7accc615b0a134c30fba203 https://git.kernel.org/stable/c/1cac04312b77fb81209da13bf5e0b83962568fcb https://git.kernel.org/stable/c/d27d48a528e437aed690f977e69a6fe73fe82ab5
