Subject: [PATCH 4/7] hwrng: optee-rng: use tee_shm_alloc_kernel_buf()
Date:   Wed,  9 Jun 2021 12:23:21 +0200
Message-Id: <20210609102324.2222332-5-jens.wiklander@linaro.org>
In-Reply-To: <20210609102324.2222332-1-jens.wiklander@linaro.org>

Uses the new simplified tee_shm_alloc_kernel_buf() function instead of
the old deprecated tee_shm_alloc() function which required specific
TEE_SHM-flags.
