Despite saying that I could take this no further, I did push on a little further and I've isolated the code that causes the rts5229 to no longer work since bede03a579b3 was applied. I've also reported the bug to LKML - see https://marc.info/?l=linux-kernel&m=159639774221968 Since reverting bede03a579b3 on recent kernels needs manual intervention, I've devised a simple patch (against linux-5.7.12). It applies correctly to 5.8.0 too but with offsets. If it doesn't apply properly on other kernels between 5.1-rc1 and 5.7.12, it is simple enough to apply manually.
