[PATCH 0/9] drm: rcar-du: Fix LVDS-related crash

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

Hello,

This patch series fixes a crash in the LVDS encoder on D3 and E3 SoCs.
See patch 1/9 for details. The next patches are additional cleanups.

Patches 4/9 to 6/9 fix incorrect usage of the devm_* API. They could be
made simpler by using the proposed drmm_* allocators for encoders and
planes ([1]), but those haven't landed yet. Not depending on them also
helps backporting those fixes to stable kernels. I will switch to the
new helpers when they will be available.
