Subject: [PATCH 4/5] net: mtk_eth_soc: fix device leak at probe
Date: Fri, 25 Jul 2025 19:12:12 +0200	[thread overview]
Message-ID: <20250725171213.880-5-johan@kernel.org> (raw)
In-Reply-To: <20250725171213.880-1-johan@kernel.org>

The reference count to the WED devices has already been incremented when
looking them up using of_find_device_by_node() so drop the bogus
additional reference taken during probe.

Fixes: 804775dfc288 ("net: ethernet: mtk_eth_soc: add support for Wireless Ethernet Dispatch (WED)")
