From 6f8d12bb1a1231dbba579932772701880745a21d Mon Sep 17 00:00:00 2001 From: Binbin Zhou Date: Wed, 28 Oct 2026 15:09:27 +0800 Subject: [PATCH] soc: loongson: loongson2_guts: Use of_root instead of own reference There is already a global of_root reference. Use that instead of getting one on our own. We don't need to care about the reference count either this way.
