From 79e3e5b894926d3c7b1efc69e0c5be723ceb88bd Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 28 Oct 2012 21:37:01 +0100 Subject: i2c-i801: Simplify dependency towards GPIOLIB Arbitrarily selecting GPIOLIB causes trouble on some architectures, so don't do that. Instead, just make the optional multiplexing code depend on CONFIG_I2C_MUX_GPIO instead of CONFIG_I2C_MUX for now. We can revisit if the i2c-i801 driver ever supports other multiplexing flavors. Also make that optional code depend on DMI, as it won't do anything without that.
