Fix up a number of coding style issues in the drivers/base/ directory that have annoyed me over the years. checkpatch.pl is now very happy. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* struct bus_type_private - structure to hold the private to the driver core portions of the bus_type structure.

|
|
* @subsys - the struct kset that defines this bus. This is the main kobject
|
|
* @drivers_kset - the list of drivers associated with this bus
|
|
* @devices_kset - the list of devices associated with this bus
|
|
* @klist_devices - the klist to iterate over the @devices_kset

|
* @klist_drivers - the klist to iterate over the @drivers_kset
|
|
* @bus_notifier - the bus notifier list for anything that cares about things
|
|
* on this bus.
|
|
* @bus - pointer back to the struct bus_type that this structure is associated
|
|
* with.
|
|
*
|
|
* This structure is the one that is the actual kobject allowing struct
|
|
* bus_type to be statically allocated safely. Nothing outside of the driver
|
|
* core should ever touch these fields.
