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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Fengguang Wu <fengguang.wu@intel.com>

If you say yes to this option, support will be included for the Intel
801 family of mainboard I2C interfaces. Specifically, the following
