[U-Boot] [PATCH 09/20] net: smsc95xx: Prepare for conversion to driver model
Simon Glass
sjg at chromium.org
Wed Jul 8 04:53:41 CEST 2015
At present struct eth_device is passed around all over the place. This does
not exist with driver model. Add explicit arguments instead, so that with
driver model we can pass the correct things.
