[PATCH 2/8] ACPI: thermal: Replace pointer with name in trip_points

[Len Brown <len.brown@xxxxxxxxx>]

From: Thomas Renninger <trenn@xxxxxxx>

For users with active thermal trip points, they need
the fan's name, rather than its address, to understand
where to look to observe and control fan state.
