It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

/**
|
|
* Scan devices on static buses.
|
|
*
|
|
* The enumeration of certain buses is purely static. The existence of
|
|
* devices on those buses can be completely determined at compile time
|
|
* and is specified in the config file. Typical examples are the 'PNP'
|
|
* devices on a legacy ISA/LPC bus. There is no need of probing of any kind,
|
|
* the only thing we have to do is to walk through the bus and
|
|
* enable or disable devices as indicated in the config file.
|
|
*
|
|
* On the other hand, some devices are virtual and their existence is
|
|
* artificial. They can not be probed at run time. One example is the
|
|
* debug device. Those virtual devices have to be listed in the config
|
|
* file under some static bus in order to be enumerated at run time.
|
|
*
|
|
* @param bus Pointer to the device to which the static buses are attached to.
