This driver does not clean up properly after leaving. Here is a list:
- Use unregister_netdev(). free_netdev() is good but not enough
- Use the above also on the other ndev in case of dual mac
- Free data.slave_data. The name of the strucre makes it look like
it is platform_data but it is not. It is just a trick!
- Free all irqs. Again: freeing one irq is good start, but freeing all
of them is better.
With this rmmod & modprobe of cpsw seems to work. The remaining issue
is:
|WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x9c/0xd4()
|sysfs: cannot create duplicate filename '/devices/ocp.2/4a100000.ethernet/4a101000.mdio'
|WARNING: at lib/kobject.c:196 kobject_add_internal+0x1a4/0x1c8()
comming from of_platform_populate() and I am not sure that this belongs
here.
