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.
