    mux: adg792a: always require I2C support · aca4e68a
    Arnd Bergmann authored
    COMPILE_TEST makes no sense when I2C is disabled, as the driver cannot compile
    in that configuration:
    
    drivers/mux/mux-adg792a.c: In function 'adg792a_write_cmd':
    drivers/mux/mux-adg792a.c:34:9: error: implicit declaration of function 'i2c_smbus_write_byte_data'; did you mean 'i2c_set_clientdata'? [-Werror=implicit-function-declaration]
    drivers/mux/mux-adg792a.o: In function `adg792a_driver_init':
    mux-adg792a.c:(.init.text+0x14): undefined reference to `i2c_register_driver'
    drivers/mux/mux-adg792a.o: In function `adg792a_probe':
    mux-adg792a.c:(.text.adg792a_probe+0x94): undefined reference to `i2c_smbus_write_byte_data'
    drivers/mux/mux-adg792a.o: In function `adg792a_set':
    mux-adg792a.c:(.text.adg792a_set+0x80): undefined reference to `i2c_smbus_write_byte_data'
