[PATCH v4 01/10] hwrng: optee-rng: use tee_shm_alloc_kernel_buf()

[Jens Wiklander <jens.wiklander@linaro.org>]

[-- Attachment #1: Type: text/plain, Size: 1189 bytes --]

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.
