-Subject: tee: add tee_shm_alloc_kernel_buf()
-
-From: Jens Wiklander <jens.wiklander@linaro.org>
-
-commit dc7019b7d0e188d4093b34bd0747ed0d668c63bf upstream.
-
-Adds a new function tee_shm_alloc_kernel_buf() to allocate shared memory
-from a kernel driver. This function can later be made more lightweight
-by unnecessary dma-buf export.
