Hello Hannes,

I've tested the MPT SAS device controller, the patch works perfectly.
However, the MPT SPI still cannot work with the hotplugging. The lspci
of the LSI SPI device is listed:

00:10.0 SCSI storage controller [0100]: LSI Logic / Symbios Logic
53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI [1000:0030] (rev 01)
        Subsystem: VMware LSI Logic Parallel SCSI Controller [15ad:1976]
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx-
        Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium
>TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 64 (1500ns min, 63750ns max)
        Interrupt: pin A routed to IRQ 17
        Region 0: I/O ports at 1400 [size=256]
        Region 1: Memory at feba0000 (64-bit, non-prefetchable) [size=128K]
        Region 3: Memory at febc0000 (64-bit, non-prefetchable) [size=128K]
        [virtual] Expansion ROM at 40008000 [disabled] [size=16K]
        Kernel driver in use: mptspi

The vendor id/device id[1000:0030] can also be found in the
mptspi_pci_table(drivers/message/fusion/mptspi.c).

PCI_VENDOR_ID_LSI_LOGIC, MPI_MANUFACTPAGE_DEVID_53C1030

If there is anything I missed in the testing? I appreciate your help.
