assert in phylink.c with lan7801 and dp83tc811 since kernel 6.18

[Sven Schuchmann <schuchmann@schleissheimer.de>]

Hello,
I have a raspberrypi and switched from kernel 6.12 to 6.18 and now I have a crash in phylink.c.

I am using a MAC:lan7801 and PHY:dp83tc811 and now it crashes like this:

it seems to happen over here:
/**
 * phylink_disconnect_phy() - disconnect any PHY attached to the phylink
 *   instance.
 * @pl: a pointer to a &struct phylink returned from phylink_create()
 *
 * Disconnect any current PHY from the phylink instance described by @pl.
 */
void phylink_disconnect_phy(struct phylink *pl)
{
      struct phy_device *phy;

      ASSERT_RTNL();

Maybe anyone can help me?
