Subject: [PATCH v2 07/12] optee: use driver internal tee_contex for some rpc
Date: Fri, 14 Jan 2022 16:08:19 +0100 [thread overview]
Message-ID: <20220114150824.3578829-8-jens.wiklander@linaro.org> (raw)
In-Reply-To: <20220114150824.3578829-1-jens.wiklander@linaro.org>
Uses the new driver internal tee_context when allocating driver private
shared memory. This decouples the shared memory object from its original
tee_context. This is needed when the life time of such a memory
allocation outlives the client tee_context.
