Subject: [PATCH v3 02/12] tee: remove unused tee_shm_pool_alloc_res_mem()
Date: Tue, 25 Jan 2022 17:29:28 +0100 [thread overview]
Message-ID: <20220125162938.838382-3-jens.wiklander@linaro.org> (raw)
In-Reply-To: <20220125162938.838382-1-jens.wiklander@linaro.org>
None of the drivers in the TEE subsystem uses
tee_shm_pool_alloc_res_mem() so remove the function.
