From 11c341b118a236423a294a7d62f71bf33e20aea3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 1 Jun 2023 10:22:30 -0600 Subject: [PATCH] gpio: Avoid using an invalid ofnode Devices do not necessarily have nodes attached to them, since they can be created from platdata. In SPL a devicetree may in fact not exist at all. Check the node before using it. This avoids failure when OF_CHECKS is enabled.
