Hi,

This patch series converts the driver to use drm managed resources to prevent
potential use-after-free issues on driver unbind/rebind and to get rid of the
usage of deprecated APIs.

Changes in v2:
  - While protecting critical sections with drm_dev_{enter,exit} I forgot to
    handle alternate return paths within the read-side critical sections, hence
    fix them.
  - Add a patch to remove explicit calls to drm_mode_config_cleanup() and switch
    to drmm_mode_config_init() explicitly.

Changes in v3:
  - Remove patches to protect platform device bound resources with
    drm_dev_{enter,exit}, since this would leave the hardware enabled when
    regularly unloading the driver e.g. via rmmod.
    Instead do this in a later series, once we got drm_dev_unplug() in place
    to deal with a regular driver shutdown.

Danilo Krummrich (5):
  drm/arm/malidp: use drmm_* to allocate driver structures
  drm/arm/malidp: replace drm->dev_private with drm_to_malidp()
  drm/arm/malidp: crtc: use drmm_crtc_init_with_planes()
  drm/arm/malidp: plane: use drm managed resources
  drm/arm/malidp: remove calls to drm_mode_config_cleanup()
