Commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703 (USB: fix up suspend and resume for PCI host controllers) attempted to fix the suspend-resume of PCI USB controllers, but unfortunately it did that incorrectly and interrupts are left enabled by the USB controllers' ->suspend_late() callback as a result. This leads to serious problems during suspend which are very difficult to debug. Fix the issue by removing the ->suspend_late() callback of PCI USB controllers and moving the code from there to the ->suspend() callback executed with interrupts enabled. Additionally, make the ->resume() callback of PCI USB controllers execute pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the full power state (PCI_D0). Signed-off-by: Rafael J.
