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().
Changes in v4:
- 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.
