[PATCH] PCI Express Hotplug: clear sticky power-fault bit
Per the PCI Express spec, the power-fault-detected bit in the slot status register can be set anytime hardware detects a power fault, regardless of whether the slot has a device populated in it or not. This bit is sticky and must be explicitly cleared. This patch is needed to allow hot-add after such a power fault has been detected.
