* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6:
  klist: fix coding style errors in klist.h and klist.c
  driver core: remove no longer used "struct class_device"
  pcmcia: remove pccard_sysfs_interface warnings
  devres: support addresses greater than an unsigned long via dev_ioremap
  kobject: do not copy vargs, just pass them around
  sysfs: sysfs_update_group stub for CONFIG_SYSFS=n
  DEBUGFS: Correct location of debugfs API documentation.
  driver core: warn about duplicate driver names on the same bus
  klist: implement klist_add_{after|before}()
  klist: implement KLIST_INIT() and DEFINE_KLIST()
  sysfs: Disallow truncation of files in sysfs

- * @node: for internal use by the driver core only.
- * @kobj: for internal use by the driver core only.
- * @groups: optional additional groups to be created
- * @dev: if set, a symlink to the struct device is created in the sysfs
- * directory for this struct class device.
- * @class_data: pointer to whatever you want to store here for this struct
- * class_device.  Use class_get_devdata() and class_set_devdata() to get and
- * set this pointer.
- * @parent: pointer to a struct class_device that is the parent of this struct
- * class_device.  If NULL, this class_device will show up at the root of the
- * struct class in sysfs (which is probably what you want to have happen.)
- * @release: pointer to a release function for this struct class_device.  If
- * set, this will be called instead of the class specific release function.
- * Only use this if you want to override the default release function, like
- * when you are nesting class_device structures.
- * @uevent: pointer to a uevent function for this struct class_device.  If
- * set, this will be called instead of the class specific uevent function.
- * Only use this if you want to override the default uevent function, like
