From d63a9e851c2c007d9129b8dbfc1af24722bd18bd Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Wed, 17 Jul 2013 13:27:59 -0700 Subject: i2c: Improve logging on failure to probe for ->class devices While writing the i2c-imc driver, I noticed that the warning message when the i2c core can't figure out how to probe is mostly useless. This trivial patch improves it.
