May be rename "max17211-battery" to "max17211" and remove no_thermal = 
true? This case thermal zone will work again. In current (mainline) 
kernel all drivers "xxxxxx-battery" (like ds2780-battery or 
ds2760-battery) compiled, but not working (not registered). They can 
start working again without thermal zone by adding no_thermal = true or 
by remove "-battery" from platform device name. Alternative limit on 
THERMAL_NAME_LENGTH may be extended.

Khm... probe/remove paired functions. I can use 
devm_power_supply_register in my code. But all other fuel gauge drivers 
use classic probe/remove pair. Which decision will be more correct?
