Subject: [PATCH 5/6] thermal/drivers/imx: Remove cooling device usage
Date: Fri, 21 Jun 2019 15:23:01 +0200
Message-ID: <20190621132302.30414-5-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20190621132302.30414-1-daniel.lezcano@linaro.org>

The cpufreq_cooling_unregister() function uses now the policy to
unregister itself. The only purpose of the cooling device pointer is
to unregister the cpu cooling device.

As there is no more need of this pointer, remove it.
