From 40e81addab7bb74d20ddf681ce9babc880a828ee Mon Sep 17 00:00:00 2001 From: Ed Swarthout Date: Wed, 11 Jul 2007 14:51:35 -0500 Subject: [PATCH] Start pci hose scan from hose->current_busno. Ensure hose->current_busno is not less than first_busno. This fixes broken board code which leaves current_busno=0 when first_busno is greater than 0 for the cases with multiple controllers.
