From d78aa650670d2257099469c344d4d147a43652d9 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 5 Sep 2018 15:57:05 +0200 Subject: drm: Add drm/drm_util.h header file We have a bunch of neat little macros all over the place which should move to kernel.h. But some of them died in bikesheds on lkml, and we need a decent home for them. Start out by moving the for_each_if macro there. v2: Rename to drm_util.h instead (Dave&Sean) Cc: Sean Paul Acked-by: Sean Paul Cc: Dave Airlie Acked-by: Dave Airlie Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20180905135711.28370-1-daniel.vetter@ffwll.ch --- include/drm/drm_util.h | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 include/drm/drm_util.h (limited to 'include/drm/drm_util.h') diff --git a/include/drm/drm_util.h b/include/drm/drm_util.h new file mode 100644 index 000000000000..88abdca89baa --- /dev/null +++ b/include/drm/drm_util.h @@ -0,0 +1,32 @@ +/* + * Internal Header for the Direct Rendering Manager + * + * Copyright 2018 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
