Hi, Sorry for the late reply.

Let's remove these prints with a simple semantic patch. This patch changes handling of -EPROBE_DEFER in the modified drivers (most don't support it and error message will no longer be printed). I cannot apply it as it is (seems that -EPROBE_DEFER handling should be audited/fixed in the affected drivers first).
