From cf67cfecc01538e32cd99e3ca00ff0e6145079ce Mon Sep 17 00:00:00 2001

Subject: [PATCH] imx-vpu-hantro: Fix ion.h header inclusion to be standard

NXP "solution" was to manually copy the header to include/linux.
Let's point the Makefile to the proper (mainline) location instead:
https://elixir.bootlin.com/linux/v4.17/source/drivers/staging/android/uapi/ion.h
