[Intel-gfx] ERR_PTR(0) in a couple of places

[Dr. David Alan Gilbert]

Hi,
  I randomly noticed there are a couple of places in the kernel that
do
   ERR_PTR(0);

and thought that was odd - shouldn't those just be NULL's ?

1) i915
  drivers/gpu/drm/i915/gt/uc/selftest_guc_multi_lrc.c : 47

    if (i <= 1)
      return ERR_PTR(0);

  from f9d72092cb490 

2) trf7970a
  drivers/nfc/trf7970a.c : 896

      trf->ignore_timeout =
         !cancel_delayed_work(&trf->timeout_work);
      trf->rx_skb = ERR_PTR(0);
      trf7970a_send_upstream(trf);
