i2c: pca954x: Fix compilation without CONFIG_GPIOLIB
The pca954x driver recently switched to the GPIO descriptor API without including the correct <linux/gpio/consumer.h> header. This breaks compilation without CONFIG_GPIOLIB. 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 Fix it by including the right header.
