Subject: [PATCH 0/2] leds: gpio: Add devlink between the leds-gpio device and the gpio used.

Hi,

When a gpio used by the leds-gpio device is removed, the leds-gpio
device continues to use this gpio. Also, when the gpio is back, the
leds-gpio still uses the old removed gpio.

A consumer/supplier relationship is missing between the leds-gpio device
(consumer) and the gpio used (supplier).

This series adds an addionnal devlink between this two device.
With this link when the gpio is removed, the leds-gpio device is also
removed.

Best regards,
Hervé Codina
