Fix the issue: "drm/imx: Crash in drm_mode_config_cleanup".
Which was documented here:
https://www.spinics.net/lists/dri-devel/msg189388.html
And tried to address with this:
https://patchwork.kernel.org/patch/10633297/ https://patchwork.kernel.org/patch/10633299/
This series fixes the possible case of use after free by adding action functions to the devres cleanup path. So it will ensure the generic cleanup code will not use the already freed memory.
