 [PATCH v2 2/3] thermal: gov_step_wise: Clarify cooling logic description
 comment

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

The cooling logic description comment next to the get_target_state()
definition is slightly ambiguous in what it means by "lower cooling
state", so clarify that by replacing the ambuguous phrase with "the
minimum applicable cooling state".

No functional impact.
