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

From: Rafael J. Wysocki <[email protected]>

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?

Assuming you will change 'board_info[board_id].name' by
'board_info[board_id]'

Hmm, why would that be required?

Anyway, though, I'm planning to use this replacement patch instead of
the $subject one:

I meant board_names[board_id] (related to the change proposed in the
patch replacement below)
