From: Daniel Vetter Date: Mon, 23 Nov 2015 09:32:40 +0000 (+0100) Subject: drm/tegra: Use unlocked gem unreferencing X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=115333042c73958cc7c2c76cddd1dfe5b1db1b7f;p=openwrt%2Fstaging%2Fblogic.git drm/tegra: Use unlocked gem unreferencing For drm_gem_object_unreference callers are required to hold dev->struct_mutex, which these paths don't. Enforcing this requirement has become a bit more strict with commit ef4c6270bf2867e2f8032e9614d1a8cfc6c71663 Author: Daniel Vetter Date: Thu Oct 15 09:36:25 2015 +0200 drm/gem: Check locking in drm_gem_object_unreference Cc: Thierry Reding Signed-off-by: Daniel Vetter Signed-off-by: Thierry Reding --- diff --git a/drivers/gpu/drm/tegra/drm.c b/drivers/gpu/drm/tegra/drm.c index dc8e7b8db54b..b26f62e7334d 100644 --- a/drivers/gpu/drm/tegra/drm.c +++ b/drivers/gpu/drm/tegra/drm.c @@ -473,7 +473,7 @@ static int tegra_gem_mmap(struct drm_device *drm, void *data, args->offset = drm_vma_node_offset_addr(&bo->gem.vma_node); - drm_gem_object_unreference(gem); + drm_gem_object_unreference_unlocked(gem); return 0; } @@ -683,7 +683,7 @@ static int tegra_gem_set_tiling(struct drm_device *drm, void *data, bo->tiling.mode = mode; bo->tiling.value = value; - drm_gem_object_unreference(gem); + drm_gem_object_unreference_unlocked(gem); return 0; } @@ -723,7 +723,7 @@ static int tegra_gem_get_tiling(struct drm_device *drm, void *data, break; } - drm_gem_object_unreference(gem); + drm_gem_object_unreference_unlocked(gem); return err; } @@ -748,7 +748,7 @@ static int tegra_gem_set_flags(struct drm_device *drm, void *data, if (args->flags & DRM_TEGRA_GEM_BOTTOM_UP) bo->flags |= TEGRA_BO_BOTTOM_UP; - drm_gem_object_unreference(gem); + drm_gem_object_unreference_unlocked(gem); return 0; } @@ -770,7 +770,7 @@ static int tegra_gem_get_flags(struct drm_device *drm, void *data, if (bo->flags & TEGRA_BO_BOTTOM_UP) args->flags |= DRM_TEGRA_GEM_BOTTOM_UP; - drm_gem_object_unreference(gem); + drm_gem_object_unreference_unlocked(gem); return 0; }
