Subject: [PATCH 0/3] Fix for drm_mode_config_cleanup issue
Date: Tue,  2 Apr 2019 15:49:01 +0200	[thread overview]
Message-ID: <20190402134904.588-1-m.grzeschik@pengutronix.de> (raw)
In-Reply-To: <0687f68004b28ed3a364b06a9eb64e2e@agner.ch>

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.

  ipuv3-crtc: add remove action for devres data
  ipuv3-ldb: add init list head on bind
