[ Upstream commit32e5a120a5] Inside tegra_fb_create(), drm_gem_object_lookup() increments ref count of the found object. But if the following size check fails then the last found object's ref count should be put there as the unreferencing loop can't detect this situation. Found by Linux Verification Center (linuxtesting.org).
