Subject: [PATCH net 7/7] net: dsa: mt7530: remove pad_setup function pointer
Date:   Sun, 26 Mar 2023 17:08:18 +0300

From: Arınç ÜNAL <arinc.unal@arinc9.com>

The pad_setup function pointer was introduced with 88bdef8be9f6 ("net: dsa:
mt7530: Extend device data ready for adding a new hardware"). It was being
used to set up the core clock and port 6 of the MT7530 switch, and pll of
the MT7531 switch.

All of these were moved to more appropriate locations so this function
pointer hasn't got a use anymore. Remove it.

Fixes: 88bdef8be9f6 ("net: dsa: mt7530: Extend device data ready for adding a new hardware")
