Subject: [PATCH v1 8/8] thermal: intel: intel_pch: Refer to thermal zone name directly

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Make intel_pch_thermal_probe() use a const char pointer instead of
a struct board_info one for accessing the thermal zone name.

No intentional functional impact.

BTW, Srinivas, I'm wondering if user space would be terribly confused by
changing this driver to use "Intel PCH" as the thermal zone name of all
of the supported platforms?
