[ Upstream commit 34731ed13e8a8ca95fa0dca466537396b5f2d1af ]
Without gpiolib, the driver fails to build:
drivers/leds/blink/leds-lgm-sso.c:123:19: error: field has incomplete type 'struct gpio_chip' struct gpio_chip chip; ^ include/linux/gpio.h:107:8: note: forward declaration of 'struct gpio_chip' struct gpio_chip; ^ drivers/leds/blink/leds-lgm-sso.c:263:3: error: implicit declaration of function 'gpiod_set_value' [-Werror,-Wimplicit-function-declaration] gpiod_set_value(led->gpiod, val); ^ drivers/leds/blink/leds-lgm-sso.c:263:3: note: did you mean 'gpio_set_value'? include/linux/gpio.h:168:20: note: 'gpio_set_value' declared here static inline void gpio_set_value(unsigned gpio, int value) ^ drivers/leds/blink/leds-lgm-sso.c:345:3: error: implicit declaration of function 'gpiod_set_value' [-Werror,-Wimplicit-function-declaration] gpiod_set_value(led->gpiod, 1); ^
Add the dependency in Kconfig.
