I guess it will be fine to either limit backporting down to just 5.0 or 4.20 (taking the kerneldoc dependency). Though probably most ideal variant will be to split the fix into two patches: first fixes the max transfer for older Tegra's and second for T194 specifically. Either way should be good enough since realistically none of upstream-supported devices should ever hit the bug (but that's not 100% of course).
