   4 Subject: [PATCH] drm/vc4: crtc: Add encoder to vc4_crtc_config_pv
   5  prototype
   6
   7 vc4_crtc_config_pv() retrieves the encoder again, even though its only
   8 caller, vc4_crtc_atomic_enable(), already did.
   9
  10 Pass the encoder pointer as an argument instead of going through all the
  11 connectors to retrieve it again.
