From 7d1d8999b4bec0ba09f935e648a688bb25596d06 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 22 Oct 2008 20:21:31 +0200 Subject: [PATCH] i2c: Constify i2c_get_clientdata's parameter i2c_get_clientdata doesn't change the i2c_client it is passed as a parameter, so it can be constified. Same for i2c_get_adapdata.
