Merge branch 'net-dsa-remove-unnecessary-set_drvdata'

Yang Yingliang says:

====================
net: dsa: remove unnecessary set_drvdata()

In this patch set, I removed all set_drvdata(NULL) functions
in ->remove() in drivers/net/dsa/.

The driver_data will be set to NULL in device_unbind_cleanup()
after calling ->remove(), so all set_drvdata(NULL) functions
in ->remove() is redundant, they can be removed.

Here is the previous patch set:
