The previous patch adding the ability to nest struct class_device
changed the paramaters to the call class_device_create().  This patch
fixes up all in-kernel users of the function.
Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This patch allows struct class_device to be nested, so that another
struct class_device can be the parent of a new one, instead of only
having the struct class be the parent.  This will allow us to
(hopefully) fix up the input and video class subsystem mess.

But please people, don't go crazy and start making huge trees of class
devices, you should only need 2 levels deep to get everything to work
(remember to use a class_interface to get notification of a new class
device being added to the system.)

Oh, this also allows us to have the possibility of potentially, someday,
moving /sys/block into /sys/class.  The main hindrance is that pesky
/dev numberspace issue...

This patch teaches "usb_device" about the new driver model wakeup support:

 - It updates device wakeup capabilities when entering a configuration
   with the WAKEUP attribute;

 - During suspend processing it consults the policy bit to see
   whether it should enable wakeup for that device.  (This resolves
   a FIXME to not assume the answer is always "yes"; some devices
   lie about supporting remote wakeup.)

Support for root hubs and the HCDs is separate (and more complex).

This is a refresh of an earlier patch to add "wakeup" support to the
PM core model.  This provides per-device bus-neutral control of the
use of wakeup events.

  * "struct device_pm_info" has two bits that are initialized as
    part of setting up the enclosing struct device:
      - "can_wakeup", reflecting hardware capabilities
      - "may_wakeup", the policy setting (when CONFIG_PM)

  * There's a writeable sysfs "wakeup" file, with one of two values:
      - "enabled", when the policy is to allow wakeup
      - "disabled", when the policy is not to allow it
      - "" if the device can't currently issue wakeups

By default, wakeup is enabled on all devices that support it.  If its
driver doesn't support it ... treat it as a bug.  :)

I was recently given an old Travan tape drive and asked to do something
useful with it.  The ide-scsi + st (+serverworks ide controller) combo
results in a hard lockup of the machine which I have not had the energy to
debug, so I turned to ide-tape (which seems to work).  The system in
question debian stable, using udev to manage /dev.

The following patch to ide-tape.c allows udev to create the cdev nodes for
my drive.
