Subject: [PATCH v1 7/7] dtpm/soc/rk3399: Add the ability to unload the module
Date: Sun, 30 Jan 2022 22:02:09 +0100	[thread overview]
Message-ID: <20220130210210.549877-7-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20220130210210.549877-1-daniel.lezcano@linaro.org>

The dtpm hierarchy can now be removed with the
dtpm_destroy_hierarchy() function. Add the module_exit() callback so
the module can be unloaded by removing the previously created
hierarchy.
