From 4329cf8613b0c7cdc020005f0e1ea7378681f1d8 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 28 Aug 2008 08:33:23 +0200 Subject: i2c: Prevent log spam on some DVB adapters Some DVB adapters do not support the special I2C transaction that we use for probing purposes. There's no point in logging this event, as there's nothing the user can do and in general there is no actual problem. So, degrade one of these messages to a debug message, and move the other one around so that it is only printed on bogus drivers.
