PCI hotplug: fix logic in Compaq hotplug controller bus speed setup
The pattern !E && !E->fld is nonsensical. The patch below updates this according to the assumption that && should be ||. But perhaps another solution was intended. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @disable and_comm@ expression E; identifier fld; @@ - !E && !E->fld + !E || !E->fld // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Reviewed-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
