From ee3939e07920f4a5405aba5f40529fd0fdd1dfb5 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 21 Jul 2014 13:15:51 +0200 Subject: [PATCH] drm/ttm: Fix a few sparse warnings The final parameter to ttm_bo_reserve() is a pointer, therefore callers should use NULL instead of 0. Fixes a bunch of sparse warnings of this type: warning: Using plain integer as NULL pointer Signed-off-by: Thierry Reding Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie --- drivers/gpu/drm/ast/ast_drv.h | 2 +- drivers/gpu/drm/bochs/bochs_fbdev.c | 2 +- drivers/gpu/drm/bochs/bochs_kms.c | 4 ++-- drivers/gpu/drm/cirrus/cirrus_drv.h | 2 +- drivers/gpu/drm/mgag200/mgag200_drv.h | 2 +- drivers/gpu/drm/nouveau/nouveau_bo.c | 6 +++--- drivers/gpu/drm/nouveau/nouveau_gem.c | 4 ++-- drivers/gpu/drm/qxl/qxl_object.h | 4 ++-- drivers/gpu/drm/vmwgfx/vmwgfx_dmabuf.c | 6 +++--- drivers/gpu/drm/vmwgfx/vmwgfx_drv.c | 2 +- drivers/gpu/drm/vmwgfx/vmwgfx_kms.c | 4 ++-- drivers/gpu/drm/vmwgfx/vmwgfx_resource.c | 2 +- 12 files changed, 20 insertions(+), 20 deletions(-) diff --git a/drivers/gpu/drm/ast/ast_drv.h b/drivers/gpu/drm/ast/ast_drv.h index 5d6a87573c33..957d4fabf1e1 100644 --- a/drivers/gpu/drm/ast/ast_drv.h +++ b/drivers/gpu/drm/ast/ast_drv.h @@ -362,7 +362,7 @@ static inline int ast_bo_reserve(struct ast_bo *bo, bool no_wait) { int ret;
