From 05a34f51ba451c65773ad6f1acf4cc089cc474d8 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 22 Oct 2008 16:44:00 -0700 Subject: [PATCH] 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/) // @disable and_comm@ expression E; identifier fld; @@ - !E && !E->fld + !E || !E->fld // Signed-off-by: Julia Lawall Reviewed-by: Matthew Wilcox Signed-off-by: Andrew Morton Signed-off-by: Jesse Barnes --- drivers/pci/hotplug/cpqphp_ctrl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/pci/hotplug/cpqphp_ctrl.c b/drivers/pci/hotplug/cpqphp_ctrl.c index ef041ca91c27..a60a25290995 100644 --- a/drivers/pci/hotplug/cpqphp_ctrl.c +++ b/drivers/pci/hotplug/cpqphp_ctrl.c @@ -1139,7 +1139,7 @@ static u8 set_controller_speed(struct controller *ctrl, u8 adapter_speed, u8 hp_ for(slot = ctrl->slot; slot; slot = slot->next) { if (slot->device == (hp_slot + ctrl->slot_device_offset)) continue; - if (!slot->hotplug_slot && !slot->hotplug_slot->info) + if (!slot->hotplug_slot || !slot->hotplug_slot->info) continue; if (slot->hotplug_slot->info->adapter_status == 0) continue;
