The patch 8c0e64ac4075b7ca870098ed2ad6089868f5fa7b ("thermal: armada: get
rid of the ->is_valid() pointer") breaks temperature readings on the
MacchiatoBIN board. Reading the temperature with
cat /sys/devices/virtual/thermal/thermal_zone*/temp
results in errors:
armada_thermal f06f808c.thermal: Temperature sensor reading not valid
armada_thermal f2400078.thermal: Temperature sensor reading not valid
armada_thermal f4400078.thermal: Temperature sensor reading not valid
The patch was meant as simple refactoring, but unfortunatelly, it reverses
the condition in armada_get_temp_legacy, so that the error is reported if
armada_is_valid returns true.
Fixes: 8c0e64ac4075 ("thermal: armada: get rid of the ->is_valid() pointer")

I sent a patch for exactly this issue on 9th November... it doesn't
seem to have made it into mainline yet.
