iio: dac: Fix build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m
This patch fixes below build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m: drivers/built-in.o: In function `ad5064_i2c_write': drivers/iio/dac/ad5064.c:608: undefined reference to `i2c_master_send' drivers/built-in.o: In function `ad5064_i2c_register_driver': drivers/iio/dac/ad5064.c:646: undefined reference to `i2c_register_driver' drivers/built-in.o: In function `ad5064_i2c_unregister_driver': drivers/iio/dac/ad5064.c:651: undefined reference to `i2c_del_driver' make: *** [vmlinux] Error 1 When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support. Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m. The real fix though is to break the driver apart into a SPI part, an I2C part and a common part. But that's something for 3.11 while this is something for 3.10/stable.
