It adds a dependency from the I2C core to GPIO so compilation for example on PPC breaks with: In file included from drivers/i2c/i2c.c:26:0: include/gpio.h:4:22: fatal error: asm/gpio.h: No such file or directory #include <asm/gpio.h> We'll need either some #ifdefery in the I2C core or some static inline wrappers in include/gpio.h for !CONFIG_GENERIC_GPIO.
