Subject: [PATCH net 03/10] ethtool: linkstate: fix unbalanced ethnl_ops_complete() on PHY lookup error
Date: Tue, 26 May 2026 08:35:26 -0700 [thread overview]
Message-ID: <20260526153533.2779187-4-kuba@kernel.org> (raw)
In-Reply-To: <20260526153533.2779187-1-kuba@kernel.org>
linkstate_prepare_data() calls ethnl_req_get_phydev() before
ethnl_ops_begin(), but routes its error path through "goto out"
which calls ethnl_ops_complete().
Fixes: fe55b1d401c6 ("ethtool: linkstate: migrate linkstate functions to support multi-PHY setups")
