Subject: [PATCH net-next v2 01/11] net: stmmac: Make stmmac_pltfr_remove() return void
The function returns zero unconditionally. Change it to return void instead
which simplifies some callers as error handing becomes unnecessary.
The function is also used for some drivers as remove callback. Switch these
to the .remove_new() callback. For some others no error can happen in the
remove callback now, convert them to .remove_new(), too.
