From 18ee49ddb0d242ed1d0e273038d5e4f6de7379d3 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Wed, 1 Oct 2008 15:41:33 +0000 Subject: phylib: rename mii_bus::dev to mii_bus::parent In preparation of giving mii_bus objects a device tree presence of their own, rename struct mii_bus's ->dev argument to ->parent, since having a 'struct device *dev' that points to our parent device conflicts with introducing a 'struct device dev' representing our own device.
