    USB: usb-storage: merge DPCM support into SDDR09 · c20b15fd
    Alan Stern authored
    The DPCM subdriver is a little peculiar, in that it's meant to support
    devices where LUN 0 is Compact Flash and uses the CB transport whereas
    LUN 1 is SmartMedia and uses the SDDR09 transport.  Thus DPCM isn't
    really a transport in itself; it's more like a demultiplexer.
    
    Much of the DPCM code is part of the SDDR09 subdriver already, and the
    remaining part is fairly small.  This patch (as1182) moves that extra
    piece into sddr09.c, thereby eliminating dpcm.c.  Also eliminated is
    the Kconfig entry for DPCM support; it is now listed as part of the
    SDDR09 entry.
    
    In order to make sure that the semantics are the same as before, each
    unusual_devs entry for DPCM is now present twice: once with DPCM
    support if SDDR09 is configured (as before), and once with the
    SINGLE_LUN flag and CB support otherwise.
