From 3360177c62e86f476c4f1a057e13163383652f7b Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sun, 7 Jan 2007 21:49:27 +0100 Subject: [PATCH] ieee1394: restore config ROM when resuming After PM suspend + resume, the local configuration ROM was not restored. This prevented remote nodes from recognizing the resuming machine.
