From 961f80f9c0c0f7c45d7818f9c9969dfaa9e4463d Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 27 Jan 2008 18:14:51 +0100 Subject: [PATCH] i2c: Drivers stop using the redundant client list The redundant i2c client list maintained by i2c-core is going away soon, so drivers should stop using it now. Instead, they can use the standard iterator provided by the device driver model (device_for_each_child).
