  now let me resend it with the following changes:

  2. remove the patch: "drm/vc4: kms: Fix IS_ERR() vs NULL check for vc4_kms"
  3. add "Reviewed-by: Abhinav Kumar <quic_abhinavk at quicinc.com>" to the second patch.

  Thanks!

- This series contains a few fixup patches, to fix IS_ERR() vs NULL check
  for drm, and avoid a potential null-ptr-defer issue, too. Thanks!
