Subject: [PATCH RESEND 0/2] leds: gpio: Add devlink between the leds-gpio device and the gpio used.
Date: Tue, 20 Feb 2024 14:39:47 +0100 [thread overview]
Message-ID: <20240220133950.138452-1-herve.codina@bootlin.com> (raw)
Hi,
Note: Resent this series with Saravana added in Cc.
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
