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 >=. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
