From b32d20dc8b187e03605f091dbde9a78676a2a642 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 3 Sep 2006 22:19:25 +0200 Subject: [PATCH] i2c-dev: attach/detach_adapter cleanups i2c-dev: attach/detach_adapter cleanups * Only print that an adapter was attached when it succeeds. * i2c_dev == NULL on detach simply means that the attach failed before, this isn't an error per se.
