Yinghai Lu 31ff2a5e42 PCI: pciehp: Stop disabling notifications during init ... During pciehp initialization, we previously wrote two hotplug commands: pciehp_probe pcie_init pcie_disable_notification pcie_write_cmd # command 1 pcie_init_notification pcie_enable_notification pcie_write_cmd # command 2 For controllers with errata like Intel CF118, we previously waited for a timeout before issuing the second hotplug command because the first command only updates interrupt enable bits and is not a "real" hotplug command, so the controller doesn't report Command Completed for it. But there's no need to disable notifications in the first place. If BIOS left them enabled, we could easily take an interrupt before disabling them, so there's no benefit in disabling them for the tiny window before we enable them. Drop the unnecessary pcie_disable_notification() call.
