Date: Mon, 28 Apr 2014 11:14:27 -0700 From: Florian Fainelli <f.fainelli@...il.com> To: netdev@...r.kernel.org Cc: davem@...emloft.net, buytenh@...tstofly.org, Florian Fainelli <f.fainelli@...il.com> Subject: [PATCH net-next 1/2] net: dsa: add ds_to_priv DSA drivers have a trick which consists in allocating "priv_size" more bytes to account for the DSA driver private context. Add a helper function to access that private context instead of open-coding it in drivers with (void *)(ds + 1).
