[PATCH v2] thermal_hwmon: Fix the 'No sensors found' error after replacing the parameter NULL by the actual device

[Cao Van Dong <cv-dong@jinso.co.jp>]

Formerly, when registering the hwmon device, we pass NULL as the device. It's not a problem.
Recently, the developer has replaced the parameter NULL as the device by the actual device.
This causes the "No sensors found" error. Therefore, instead of using the device we will use pass
the parent of that device as parameter. This will sync with the processor on the hwmon core.
This patch is to fix this error.

This patch is based on the v4.19-rc3 tag.
