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

* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6: (36 commits)
  Driver core: show drivers in /sys/module/
  Documentation/driver-model/platform.txt update/rewrite
  Driver core: platform_driver_probe(), can save codespace
  driver core: Use klist_remove() in device_move()
  driver core: Introduce device_move(): move a device to a new parent.
  Driver core: make drivers/base/core.c:setup_parent() static
  driver core: Introduce device_find_child().
  sysfs: sysfs_write_file() writes zero terminated data
  cpu topology: consider sysfs_create_group return value
  Driver core: Call platform_notify_remove later
  ACPI: Change ACPI to use dev_archdata instead of firmware_data
  Driver core: add dev_archdata to struct device
  Driver core: convert sound core to use struct device
  Driver core: change mem class_devices to be real devices
  Driver core: convert fb code to use struct device
  Driver core: convert firmware code to use struct device
  Driver core: convert mmc code to use struct device
  Driver core: convert ppdev code to use struct device
  Driver core: convert PPP code to use struct device
  Driver core: convert cpuid code to use struct device
