My question has a part 'depending on the hardware', so possibly the
relevant code could check what the hardware is. Likewise, the code
could check the kernel version. More generally, when something can be
decided manually, it can often be detected automatically with some
work. I'm not seeing any impossibility here.
Also, again, why are you submitting this work-around when it appears to
be simply a kernel bug that needs a kernel package to be updated and
maybe a devicetree fix to be backported? As written in a previous response:
