This adds kernel regression and breaks kernel build (it is generally good to
grep kernel tree for the existing users before doing changes like the above):

drivers/ide/ide-pci-generic.c:

        { PCI_VDEVICE(TOSHIBA,  PCI_DEVICE_ID_TOSHIBA_PICCOLO),          4 },
        { PCI_VDEVICE(TOSHIBA,  PCI_DEVICE_ID_TOSHIBA_PICCOLO_1),        4 },
        { PCI_VDEVICE(TOSHIBA,  PCI_DEVICE_ID_TOSHIBA_PICCOLO_2),        4 },

Please fix your patch.
