The hwmon-next branch is based on v5.5-rc1. It might be better to either
merge hwmon-next into mainline, or to apply the drivetemp patch to mainline,
and test the result. I have seen some (unrelated) weird tracebacks
in the driver core with v5.5-rc1, so that may not be the best baseline
for a test.
