Hi,

With CONFIG_OF_DYNAMIC enabled, I got the following. Is this a known issue?

Well, that option isn't enabled in tegra_defconfig so it's unlikely
anyone working on Tegra would have run into it. Best ask on the ARM or
devicetree-discuss mailing list if you want, or just send a patch to fix it.

Ok, I'll check if refcounting is ok or not.
