From e3aa76644c2af14631a1fb5ba17022e0a396a6c4 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 22 Apr 2022 15:15:55 +0200 Subject: [PATCH] led: gpio: Check device compatible string to determine the top level node Since 2d1deaf88ed ("led: gpio: Drop duplicate OF "label" property parsing"), all LED nodes have some sort of label. Use device_is_compatible(..."leds-gpio") to determine whether this is a top-level node, since it is only the top level node which is compatible with "leds-gpio", the GPIO LEDs subnodes are not.
