The patch below does not apply to the 5.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.

We are in receipt of a bug report which cites this patch as the fix.

Does the bug report really say that this issue is present in the 5.4 kernel tree? Anything older?

Not specifically, but the commit referenced in the Fixes tag landed in v5.5. and was successfully back-ported to v5.4.144.
