Subject: [PATCH net] net: lan966x: enforce phy-mode presence
Date: Thu, 4 Sep 2025 13:38:34 -0700 [thread overview]
Message-ID: <20250904203834.3660-1-rosenp@gmail.com> (raw)
The documentation for lan966x states that phy-mode is a required
property but the code does not enforce this. Add an error check.
Fixes: db8bcaad5393 ("net: lan966x: add the basic lan966x driver")
Signed-off-by: Rosen Penev <rosenp@gmail.com>
