I think if anything this bug report itself should be reassigned to
linux-headers-5.3.0-1-arm64.
However, that package looks like it's about to be superceded by
linux-headers-5.3.0-2-arm64 because of a recent ABI bump to the kernel
in unstable.
I know this is a lot to ask, but can you take the following steps?
* upgrade your system to linux-image-5.3.0-2-arm64 and reboot into the
new kernel
* make sure you have linux-headers-5.3.0-2-arm64 installed
* retry building the various kernel modules that were failing?
If they are still failing for you on 5.3.0-2-arm64, i recommend
reassigning this bug report to linux-headers-5.3.0-2-arm64.
Sorry to not have the equipment up and running to test these things
myself. I appreciate your persevering on this bug report, let's get it
figured out (and hopefully, fixed)!
All the best,
