Subject: [PATCH net-next] net: dsa: remove dev arg of dsa_register_switch
The current dsa_register_switch function takes a useless struct device
pointer argument, which always equals ds->dev.
Drivers either call it with ds->dev, or with the same device pointer
passed to dsa_switch_alloc, which ends up being assigned to ds->dev.
This patch removes the second argument of the dsa_register_switch and
_dsa_register_switch functions.
