[PATCH] USB: add missing pci_disable_device for PCI-based USB HCD

From: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com>

This patch adds pci_disable_device() into usb_hcd_pci_remove().

If the driver decides to stop using the device, it should call
pci_disable_device() to deallocate any IRQ resources, disable PCI
bus-mastering, etc.
