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.
