From 25d2f85bf57fb0a56eeb60d00465b99f069f4376 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 6 Oct 2021 10:54:51 -0400 Subject: include: Introduce linux-uapi for non-drm-uapi files. sync_file.h is needed for dma-buf, but it is part of the linux-uapi include dir. The patch aims to have a drm-uapi directory that is a pure copy of the generated drm-uapi include dir.
