Merge tag 'driver-core-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here's the big driver core merge for 3.11-rc1

  Lots of little things, and larger firmware subsystem updates, all
  described in the shortlog.  Nice thing here is that we finally get rid
  of CONFIG_HOTPLUG, after 10+ years, thanks to Stephen Rohtwell (it had
  been always on for a number of kernel releases, now it's just
  removed)"

* tag 'driver-core-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (27 commits)
  driver core: device.h: fix doc compilation warnings
  firmware loader: fix another compile warning with PM_SLEEP unset
  build some drivers only when compile-testing
  firmware loader: fix compile warning with PM_SLEEP set
  kobject: sanitize argument for format string
  sysfs_notify is only possible on file attributes
  firmware loader: simplify holding module for request_firmware
  firmware loader: don't export cache_firmware and uncache_firmware
  drivers/base: Use attribute groups to create sysfs memory files
  firmware loader: fix compile warning
  firmware loader: fix build failure with !CONFIG_FW_LOADER_USER_HELPER
  Documentation: Updated broken link in HOWTO
  Finally eradicate CONFIG_HOTPLUG
  driver core: firmware loader: kill FW_ACTION_NOHOTPLUG requests before suspend
  driver core: firmware loader: don't cache FW_ACTION_NOHOTPLUG firmware
  Documentation: Tidy up some drivers/base/core.c kerneldoc content.
  platform_device: use a macro instead of platform_driver_register
  firmware: move EXPORT_SYMBOL annotations
  firmware: Avoid deadlock of usermodehelper lock at shutdown
  dell_rbu: Select CONFIG_FW_LOADER_USER_HELPER explicitly
