From 35e1801ea637810830e653ffe7ff62c7048ae03a Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Wed, 11 Feb 2009 21:13:45 +0100 Subject: [PATCH] PCI hotplug: shpchp: fix bus number check to avoid false positive With for (busnr = 0; busnr <= end; busnr++) { ... } busnr reaches end + 1 after the loop. So fix the "no busses available" check to look for just busnr > end rather than >=.
