Subject: PCI hotplug: shpchp: fix bus number check to avoid false positive
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=35e1801ea637810830e653ffe7ff62c7048ae03a;p=linux-2.6-omap-h63xx.git

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 >=.
