[PATCH] platform: arm64: qcom-hamoa-ec: Register cooling devices with their name

[Anvesh Jain P]

Each fan is registered as a thermal cooling device using
devm_thermal_of_cooling_device_register(). When the thermal core gained
cooling device ID support, the helper's prototype changed: its second
argument became a 'u32 cdev_id' and its third a 'const char *type',
replacing the previous 'struct device_node *np'.

The resulting semantic conflict between the EC driver and the reworked
thermal helper was resolved while merging the drivers-x86 tree into
linux-next by passing NULL as the 'type' argument, dropping the per-fan
'name' string. As a result every fan is registered as a cooling device
with an empty name.

Pass 'name' as the 'type' argument so the cooling devices are registered
with their intended "qcom_ec_fan_<n>" names.
