Subject: [PATCH net] net: bcmgenet: Remove phy_stop() from bcmgenet_netif_stop()
Date: Thu, 4 May 2023 16:07:27 -0700 [thread overview]
Message-ID: <20230504230727.729539-1-f.fainelli@gmail.com> (raw)
The call to phy_stop() races with the later call to phy_disconnect(),
resulting in concurrent phy_suspend() calls being run from different
CPUs. The final call to phy_disconnect() ensures that the PHY is
stopped and suspended, too.
Fixes: c96e731c93ff ("net: bcmgenet: connect and disconnect from the PHY state machine")
Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
