Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6

* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6: (61 commits)
  Dynamic debug: fix pr_fmt() build error
  Dynamic debug: allow simple quoting of words
  dynamic debug: update docs
  dynamic debug: combine dprintk and dynamic printk
  sysfs: fix some bin_vm_ops errors
  kobject: don't block for each kobject_uevent
  sysfs: only allow one scheduled removal callback per kobj
  Driver core: Fix device_move() vs. dpm list ordering, v2
  Driver core: some cleanup on drivers/base/sys.c
  Driver core: implement uevent suppress in kobject
  vcs: hook sysfs devices into object lifetime instead of "binding"
  driver core: fix passing platform_data
  driver core: move platform_data into platform_device
  sysfs: don't block indefinitely for unmapped files.
  driver core: move knode_bus into private structure
  driver core: move knode_driver into private structure
  driver core: move klist_children into private structure
  driver core: create a private portion of struct device
  driver core: remove polling for driver_probe_done(v5)
  sysfs: reference sysfs_dirent from sysfs inodes
  ...

Fixed conflicts in drivers/sh/maple/maple.c manually
