[PATCH] leds: gpio: Skip unavailable LEDs during shutdown

[PATCH] leds: gpio: Skip unavailable LEDs during shutdown

[Steve Dunnagan]

gpio_led_probe() leaves an error-valued GPIO descriptor in the LED
data when an unavailable platform-data LED is skipped.

The entry remains included in priv->num_leds, so gpio_led_shutdown()
later passes the error pointer to gpio_led_set(), producing:

gpiod_set_value: invalid GPIO (errorpointer: -ENOENT)

Skip entries with error-valued GPIO descriptors during shutdown.

Fixes: 45d4c6de4e49 ("leds: gpio: Try to lookup gpiod from device")
