Merge tag 'driver-core-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core patches from Greg KH:
 "Here's the big driver core pull request for 3.12-rc1.

  Lots of tiny changes here fixing up the way sysfs attributes are
  created, to try to make drivers simpler, and fix a whole class race
  conditions with creations of device attributes after the device was
  announced to userspace.

  All the various pieces are acked by the different subsystem
  maintainers"

* tag 'driver-core-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (119 commits)
  firmware loader: fix pending_fw_head list corruption
  drivers/base/memory.c: introduce help macro to_memory_block
  dynamic debug: line queries failing due to uninitialized local variable
  sysfs: sysfs_create_groups returns a value.
  debugfs: provide debugfs_create_x64() when disabled
  rbd: convert bus code to use bus_groups
  firmware: dcdbas: use binary attribute groups
  sysfs: add sysfs_create/remove_groups for when SYSFS is not enabled
  driver core: add #include <linux/sysfs.h> to core files.
  HID: convert bus code to use dev_groups
  Input: serio: convert bus code to use drv_groups
  Input: gameport: convert bus code to use drv_groups
  driver core: firmware: use __ATTR_RW()
  driver core: core: use DEVICE_ATTR_RO
  driver core: bus: use DRIVER_ATTR_WO()
  driver core: create write-only attribute macros for devices and drivers
  sysfs: create __ATTR_WO()
  driver-core: platform: convert bus code to use dev_groups
  workqueue: convert bus code to use dev_groups
  MEI: convert bus code to use dev_groups
