    [PATCH] s390: 3215 driver. · d022be21
    Martin Schwidefsky authored
    Convert 3215 console driver to new channel subsystem driver
    
    this adds support for the driver model to the 3215 driver. The console
    is one of the biggest problems because the regular device detection
    is now done at initcall time although we actually want full
    support for channel attached console devices as early as possible.
    con3215_init() now uses a special ccw_device_probe_console() function
    to do an early initialization of a single device.
    
    The main backdraw for users is that the console can no longer
    be autodetected when not running under VM. LPAR or P390 users
    with a channel attached console now have to specify
    console_device=f00 as a kernel parameter.
