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:
  - drop patch "drm/arm/hdlcd: crtc: use drmm_crtc_init_with_planes()"

Changes in v3:
  - Fix alternate return paths in srcu read-side critical sections causing a
    stall when unregistering the driver.
  - Fix potential null pointer dereference in hdlcd_crtc_cleanup() introduced
    dropping the patch in v2.
  - Add a patch to remove explicit calls to drm_mode_config_cleanup().

Danilo Krummrich (7):
  drm/arm/hdlcd: use drmm_* to allocate driver structures
  drm/arm/hdlcd: replace drm->dev_private with drm_to_hdlcd_priv()
  drm/arm/hdlcd: plane: use drm managed resources
  drm/arm/hdlcd: use drm_dev_unplug()
  drm/arm/hdlcd: crtc: protect device resources after removal
  drm/arm/hdlcd: debugfs: protect device resources after removal
  drm/arm/hdlcd: remove calls to drm_mode_config_cleanup()
