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

* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6: (36 commits)
  SCSI: convert struct class_device to struct device
  DRM: remove unused dev_class
  IB: rename "dev" to "srp_dev" in srp_host structure
  IB: convert struct class_device to struct device
  memstick: convert struct class_device to struct device
  driver core: replace remaining __FUNCTION__ occurrences
  sysfs: refill attribute buffer when reading from offset 0
  PM: Remove destroy_suspended_device()
  Firmware: add iSCSI iBFT Support
  PM: Remove legacy PM (fix)
  Kobject: Replace list_for_each() with list_for_each_entry().
  SYSFS: Explicitly include required header file slab.h.
  Driver core: make device_is_registered() work for class devices
  PM: Convert wakeup flag accessors to inline functions
  PM: Make wakeup flags available whenever CONFIG_PM is set
  PM: Fix misuse of wakeup flag accessors in serial core
  Driver core: Call device_pm_add() after bus_add_device() in device_add()
  PM: Handle device registrations during suspend/resume
  block: send disk "change" event for rescan_partitions()
  sysdev: detect multiple driver registrations
  ...

Fixed trivial conflict in include/linux/memory.h due to semaphore header
file change (made irrelevant by the change to mutex).
