For some reason I don't see this patch in my inbox. Maybe it will
arrive later. Immediate response: please add
devm_thermal_add_hwmon_sysfs().

NAK. The kernel is expected to build and work after each commit.
Otherwise git-bisecting the kernel becomes impossible.
So, please rework your series in a way that there are no compilation
errors after any of the patches. The easiest way would be to rearrange
your patches in 3-1-2 order.
