An 'out-of-tree' message does not indicate an error. It is informing
you that the module being loaded is not a part of the kernel source
tree, but an 'out-of-tree' one, i.e. your custom module whose source
code resides say in your home directory.

To verify your module has been loaded successfully, run 'lsmod | grep
your_module_name' after loading it with 'insmod'.

Hope this helps.
