Subject: [PATCH 0/3] drm/vc4: use drm managed resources

This patch series converts DRM modeset object allocations from devm_*()
to drmm_*() memory allocators, or their corresponding convenience
wrappers, respectively, in order to tie the release action to the
underlaying struct drm_device.

This can prevent potential use-after free issues on driver unload or
EPROBE_DEFERRED backoff.

  drm/vc4: plane: use drm managed resources
  drm/vc4: crtc: use drm managed resources
  drm/vc4: encoder: use drm managed resources
