i2c: mux: pca954x: fix dependencies
This driver causes the following randconfig build error: drivers/i2c/muxes/i2c-mux-pca954x.c: In function ‘pca954x_probe’: drivers/i2c/muxes/i2c-mux-pca954x.c:204:2: error: implicit declaration of function ‘devm_gpiod_get’ [-Werror=implicit-function-declaration] gpio = devm_gpiod_get(&client->dev, "reset"); ^ drivers/i2c/muxes/i2c-mux-pca954x.c:204:7: warning: assignment makes pointer from integer without a cast [enabled by default] gpio = devm_gpiod_get(&client->dev, "reset"); ^ drivers/i2c/muxes/i2c-mux-pca954x.c:206:3: error: implicit declaration of function ‘gpiod_direction_output’ [-Werror=implicit-function-declaration] gpiod_direction_output(gpio, 0); ^ cc1: some warnings being treated as errors make[3]: *** [drivers/i2c/muxes/i2c-mux-pca954x.o] Error 1 This is because it is getting compiled without gpiolib, so introduce an explicit dependency.
