Hello Brendan, as I can still see this code in the upstream kernel code[1] would you mind to give the latest mainline kernel[2] a try? https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10-rc4/
If this issue still exist in upstream, it's better to open an upstream bug: https://bugzilla.kernel.org/ Thanks!
