From 72b9ff0612ad8fc969b910cd00ac16b57a1a9ba4 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 30 Mar 2016 11:40:43 +0200 Subject: [PATCH] drm/udl: 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: stable@vger.kernel.org Signed-off-by: Daniel Vetter Signed-off-by: Dave Airlie --- drivers/gpu/drm/udl/udl_fb.c | 2 +- drivers/gpu/drm/udl/udl_gem.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/udl/udl_fb.c b/drivers/gpu/drm/udl/udl_fb.c index 33239a2b264a..fd1eb9d03f0b 100644 --- a/drivers/gpu/drm/udl/udl_fb.c +++ b/drivers/gpu/drm/udl/udl_fb.c @@ -536,7 +536,7 @@ static int udlfb_create(struct drm_fb_helper *helper, out_destroy_fbi: drm_fb_helper_release_fbi(helper); out_gfree: - drm_gem_object_unreference(&ufbdev->ufb.obj->base); + drm_gem_object_unreference_unlocked(&ufbdev->ufb.obj->base); out: return ret; } diff --git a/drivers/gpu/drm/udl/udl_gem.c b/drivers/gpu/drm/udl/udl_gem.c index 2a0a784ab6ee..d7528e0d8442 100644 --- a/drivers/gpu/drm/udl/udl_gem.c +++ b/drivers/gpu/drm/udl/udl_gem.c @@ -52,7 +52,7 @@ udl_gem_create(struct drm_file *file, return ret; } - drm_gem_object_unreference(&obj->base); + drm_gem_object_unreference_unlocked(&obj->base); *handle_p = handle; return 0; } -- GitLab
