[PATCH 2/2] ledtrig-gpio: 0 is a valid GPIO number

GPIO number 0 is a valid case to handle. Use -1 as initial value and use gpio_is_valid() to determine validity of the GPIO number. Signed-off-by: Kun Yi Change-Id: I4a29f98b237fd0d8ba4dd2a28219d4429f2ccfff --- drivers/leds/trigger/ledtrig-gpio.c | 16 +--- 1 file changed, 5
