Subject: [PATCH v3 3/7] thermal/drivers/cpu_cooling: Remove pointless field
Date: Thu,  5 Apr 2018 18:16:40 +0200	[thread overview]
Message-ID: <1522945005-7165-4-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1522945005-7165-1-git-send-email-daniel.lezcano@linaro.org>

The structure cpufreq_cooling_device provides a backpointer to the thermal
device but this one is used for a trace and to unregister. For the trace,
we don't really need this field and the unregister function as the same
pointer passed as parameter. Remove it.
