The issue is in the iwlwifi wireless driver, specifically the error -61
(ENODATA) is being reported by the call to iwl_mvm_tzone_get_temp() in
in drivers/net/wireless/intel/iwlwif/mvm/tt.c
Looking at this failure case it could be because there is a mismatch
between the expected firmware blob and the actual installed (nor not
installed) firmware blob for this driver.
Can you try installing or re-installing the linux-firmware package to
see if this helps. You may need to re-boot the machine for this to be
activated.
I suggest using:
sudo apt-get install --reinstall linux-firmware
Let us know if this allows one to read cat /sys/class/thermal/thermal_zone4/type
iwlwifi_1
