Let's fix this while we're at it. Signed-off-by: Lyude Paul --- V3: * Don't use devm, that will just break during unbind (Sashiko). V5: * Fix silly rebasing error * Go back to the old style of error handling since we're not using a second allocation for drm_driver anymore. drivers/gpu/drm/nouveau/nouveau_drm.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/nouveau/nouveau_drm.c b/drivers/gpu/drm/nouveau/nouveau_drm.c index 4d1ad718e09b7..a348115518ec4 100644 --- a/drivers/gpu/drm/nouveau/nouveau_drm.c +++ b/drivers/gpu/drm/nouveau/nouveau_drm.c @@ -749,7 +749,8 @@ nouveau_drm_device_new(const struct drm_driver *drm_driver, struct device *paren drm->dev = drm_dev_alloc(drm_driver, parent); if (IS_ERR(drm->dev)) { ret = PTR_ERR(drm->dev); - goto done; + kfree(drm); + return ERR_PTR(ret); } drm->dev->dev_private = drm; -- 2.55.0
