Hello
Thx for this patch train, maybe I missed the cover letter. In my opinion the proposed change is intrusive but I can accept. It could be great to enhance the platform remove functions to fail in case of an expected case occurs.
+ .remove_new = stmmac_pltfr_remove,
To be honest, I do not like to see: ".remove_new" as hook
Regards

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.
