[PATCH drm-misc-next v3 0/5] drm/arm/malidp: use drm managed resources

From: Danilo Krummrich

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.
