Please do not top-post. As I already mentioned, the purpose of the 'loading out-of-tree module taints kernel' message is to inform the users of the i2c_client driver that it is not a part of the kernel source tree. It does not indicate a problem. So, to the best of my knowledge, the message won't go away. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
