fs_enet_probe() allocates the platform information structure with
kzalloc_obj() and stores it in fep->fpi.
The probe failure paths release this allocation with kfree(). However,
after a successful probe, fs_enet_remove() tears down the network
device without freeing fep->fpi, leaving the platform information
structure allocated after driver removal.
Free fep->fpi before releasing the network device.
This issue was found by manual code inspection.
