Subject: [PATCH leds v2 40/50] leds: ns2: use devres API for getting GPIO descriptors
Date:   Fri, 18 Sep 2020 00:33:28 +0200
Message-Id: <20200917223338.14164-41-marek.behun@nic.cz>

This drivers leaks GPIO descriptors on driver removal. Use devres API
function devm_gpiod_get_from_of_node instead of gpiod_get_from_of_node
to avoid this.
