Subject: [PATCH v1 3/7] powercap/dtpm: Fixup kfree for virtual node
Date: Sun, 30 Jan 2022 22:02:05 +0100	[thread overview]
Message-ID: <20220130210210.549877-3-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20220130210210.549877-1-daniel.lezcano@linaro.org>

When the node is virtual there is no release function associated which
can free the memory.

Free the memory when no 'ops' exists.
