Subject: [PATCH v1 5/7] powercap/dtpm: Move the 'root' reset place
Date: Sun, 30 Jan 2022 22:02:07 +0100 [thread overview]
Message-ID: <20220130210210.549877-5-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20220130210210.549877-1-daniel.lezcano@linaro.org>
The 'root' node is checked everytime a dtpm node is destroyed.
When we reach the end of the hierarchy destruction function, we can
unconditionnaly set the 'root' node to NULL again.
