Subject: [PATCH] staging: fsl_ppfe/eth: unregister netdev after pfe_phy_exit
rmmod pfe.ko throws below warning:
kernfs: can not remove 'phydev', no directory
------------[ cut here ]------------
WARNING: CPU: 0 PID: 2230 at fs/kernfs/dir.c:1481
kernfs_remove_by_name_ns+0x90/0xa0
This is caused when the unregistered netdev structure is accessed to
disconnect phy.
Resolve the issue by unregistering netdev after disconnecting phy.
