[PATCH drm-misc-next v2 0/9] drm/fsl-dcu: use drm managed resources

From: Danilo Krummrich
Date: Sat Oct 01 2022 - 10:58:30 EST


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.

Danilo Krummrich (9):
drm/fsl-dcu: use drmm_* to allocate driver structures
drm/fsl-dcu: replace drm->dev_private with drm_to_fsl_dcu_drm_dev()
drm/fsl-dcu: crtc: use drmm_crtc_init_with_planes()
drm/fsl-dcu: plane: use drm managed resources
drm/fsl-dcu: use drm_dev_unplug()
drm/fsl-dcu: plane: protect device resources after removal
drm/fsl-dcu: crtc: protect device resources after removal
drm/fsl-dcu: remove trailing return statements
drm/fsl-dcu: remove calls to drm_mode_config_cleanup()
