If anyone has any objections, please let me know. ------------------ From: Florian Fainelli [ Upstream commit daab3349ad1a69663ccad278ed71d55974d104b4 ] We are not releasing the link GPIO descriptor with gpiod_put() which results in subsequent probing to get -EBUSY when calling fwnode_get_named_gpiod(). Fix this by doing the release in phylink_destroy(). Fixes: 9525ae83959b ("phylink: add phylink infrastructure") Signed-off-by: Florian Fainelli Signed-off-by: David S.
