hwmon: fix potential sensor registration fail if of_node is missing

Browse source

[ Upstream commit 2315332efc ]

It is not sufficient to check of_node in current device.
In some cases, this would cause the sensor registration to fail.

This patch looks for device's ancestors to find a valid of_node if any.
