Wu Fengguang 341203167f Thermal: fix platform_no_drv_owner.cocci warnings
drivers/thermal/int340x_thermal/int3403_thermal.c:468:3-8: No need to set .owner here. The core will do it.

 Remove .owner field if calls are used which set it automatically

Markus Elfring 931b9c86d9 thermal: int3403: Delete a check before thermal_zone_device_unregister()
The thermal_zone_device_unregister() function tests whether its argument
is NULL and then returns immediately. Thus the test around the call
is not needed.

This issue was detected by using the Coccinelle software.

lan,Tianyu 225112a569 Thermal/int3403: Fix thermal hysteresis unit conversion
Thermal hysteresis represents a temperature difference.
But the original code treats it as a temperature value,
Convert it from tenths of degree Kelvin to Milli-Celsius
by deducing 273200. This is not right.

Kelvin and Celsius have same degree size. From temperature
difference view, the conversion between tenths of degree
Kelvin unit and Milli-Celsius unit is just to multiply 100.

Lan Tianyu 4384b8fe16 Thermal: introduce int3403 thermal driver
ACPI INT3403 device object can be used to retrieve temperature date
from temperature sensors present in the system, and to expose
device' performance control.

The previous INT3403 thermal driver supports temperature reporting only,
thus remove it and introduce this new & enhanced one.
