From 51d95709dddf7fdf6769a547de37a9c98edf8df9 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 9 Mar 2013 08:16:49 +0000 Subject: i2c: Make the return type of i2c_del_mux_adapter() void i2c_del_mux_adapter always returns 0 and none of it current users check its return value anyway. It is also an essential requirement of the Linux device driver model, that functions which may be called from a device's remove callback to free resources provided by the device, are not allowed to fail. This is the case for i2c_del_mux_adapter(), so make its return type void to make the fact that it won't fail explicit.
