Dan Carpenter 3d308a1631 dma-buf: fix an error pointer vs NULL bug ... commit 00ae1491f9 upstream. Smatch detected potential error pointer dereference. drivers/gpu/drm/drm_syncobj.c:888 drm_syncobj_transfer_to_timeline() error: 'fence' dereferencing possible ERR_PTR() The error pointer comes from dma_fence_allocate_private_stub(). One caller expected error pointers and one expected NULL pointers. Change it to return NULL and update the caller which expected error pointers, drm_syncobj_assign_null_handle(), to check for NULL instead.
