From e2ca307439fb9df922c3e8891289a2ac05812fb7 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 2 Mar 2010 12:23:43 +0100 Subject: [PATCH] i2c: Separate Kconfig option for i2c-smbus Having a separate Kconfig option for i2c-smbus makes it possible to build that support as a module even when i2c-core itself is built-in. Bus drivers which implement SMBus alert should select this option, so in most cases this option is hidden and the user doesn't have to care about it.
