[PATCH v2 1/8] tee: allow a driver to allocate a tee_device without a pool

From: Amirreza Zarrabi <hidden>
Date: 2025-02-03 02:44:41
Also in: linux-arm-msm, linux-doc, lkml, op-tee
Subsystem: tee subsystem, the rest · Maintainers: Jens Wiklander, Linus Torvalds

A TEE driver doesn't always need to provide a pool if it doesn't
support memory sharing ioctls and can allocate memory for TEE
messages in another way. Although this is mentioned in the
documentation for tee_device_alloc(), it is not handled correctly.
