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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
