[PATCH net-next] net: dsa: remove dev arg of dsa_register_switch

From: Vivien Didelot
Date: Fri May 26 2017 - 21:27:14 EST


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.
