From e31a127c2f99b9cb9abc99a1ec22b75194890800 Mon Sep 17 00:00:00 2001 From: Jody McIntyre Date: Fri, 30 Sep 2005 11:59:09 -0700 Subject: [PATCH] ieee1394: skip unnecessary pause when scanning config ROMs Skip a superfluous pause that occured when the config ROM of a node was scanned unsuccessfully. This also occurs if a node without link wrongly enables its "link active" self ID flag. A GWCTech 6-port hub does this.
