[RFC Patch net-next v2 11/15] net: dsa: microchip: common dsa_switch_ops for ksz switches

Arun Ramadoss
2022-05-30T10:45:40Z

At present, ksz8795.c and ksz9477.c have separate dsa_switch_ops
structure initialization. This patch modifies the files such a way that
ksz switches has common dsa_switch_ops in the ksz_common.c file.
