From 17ea41eabbffc5910e9159d95e8b1d2379f91ee9 Mon Sep 17 00:00:00 2001 From: Tianling Shen Date: Fri, 27 Sep 2024 15:54:04 +0800 Subject: [PATCH] kernel: make 'no port node found' output a debug message There are cases where an unavailable port is not an error, making this error message a false-positive. The kernel log is flooded with the messages like: OF: graph: no port node found in /soc@0/bus@42000000/i2c@42530000/usb-typec@50 Silence this message by making it a debug message.
