From 1c81128dcd3a723f75d554b0a8d87101d7dd3663 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sat, 15 Jun 2013 20:33:44 +0200 Subject: pnp: Add some default functions to enter/exit config state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement some common default functions to enter and exit the configuration state. Also provide default pnp_mode_ops for common enter()/exit() function pairs.
