    firewire: introduce fw_driver.probe and .remove methods · 94a87157
    Stefan Richter authored
    FireWire upper layer drivers are converted from generic
        struct driver.probe() and .remove()
    to bus-specific
        struct fw_driver.probe() and .remove().
    
    The new .probe() adds a const struct ieee1394_device_id *id argument,
    indicating the entry in the driver's device identifiers table which
    matched the fw_unit to be probed.  This new argument is used by the
    snd-firewire-speakers driver to look up device-specific parameters and
    methods.  There is at least one other FireWire audio driver currently in
    development in which this will be useful too.
    
    The new .remove() drops the unused error return code.
    
    Although all in-tree drivers are being converted to the new methods,
    support for the old methods is left in place in this commit.  This
    allows public developer trees to merge this commit and then move to the
    new fw_driver methods.
