[alsa-devel] [PATCH 5/9] ASoC: Only compile adav80x codec when a bus is defined

If !CONFIG_SPI and !CONFIG_I2C* then there is no point adding support
for the adav80x codec as it relies on a bus to operate. This patch
fixes the build warnings below when SPI and I2C are not specified in
the configuration.

sound/soc/codecs/adav80x.c:842:22: warning: ‘adav80x_bus_probe’ defined but not used [-Wunused-function]
sound/soc/codecs/adav80x.c:863:22: warning: ‘adav80x_bus_remove’ defined but not used [-Wunused-function]
