From cf4441503e20a0c0a36e0a98dcf57de3d3844c91 Mon Sep 17 00:00:00 2001 From: Balint Dobszay Date: Mon, 25 Mar 2024 16:11:02 +0100 Subject: tee: optee: Move pool_op helper functions Move the pool alloc and free helper functions from the OP-TEE driver to the TEE subsystem, since these could be reused in other TEE drivers. This patch is not supposed to change behavior, it's only reorganizing the code.
