The LED's "label" property has been deprecated in upstream by: |commit c5d18dd6b64e09dd6984bda9bdd55160af537a8c |Author: Jacek Anaszewski <jacek.anaszewski@gmail.com> |Date: Sun Jun 9 20:19:04 2019 +0200 | | dt-bindings: leds: Add properties for LED name construction | | Introduce dedicated properties for conveying information about | LED function and color. Mark old "label" property as deprecated. | | Additionally function-enumerator property is being provided | for the cases when neither function nor color can be used | for LED differentiation. in order to be somewhat prepared, this patch adds a fallback as a last resort to make the current led code work by falling back to the node-name as the "label".
