Merge tag 'driver-core-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core update from Greg Kroah-Hartman:
 "Here's the merge request for the driver core tree for 3.10-rc1

  It's pretty small, just a number of driver core and sysfs updates and
  fixes, all of which have been in linux-next for a while now.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

Fixed conflict in kernel/rtmutex-tester.c, the locking tree had a better
fix for the same sysfs file mode problem.

* tag 'driver-core-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
  PM / Runtime: Idle devices asynchronously after probe|release

  driver core: devtmpfs: fix compile failure with CONFIG_UIDGID_STRICT_TYPE_CHECKS
  devtmpfs: add base.h include
  driver core: add uid and gid to devtmpfs
  sysfs: check if one entry has been removed before freeing
  sysfs: fix crash_notes_size build warning
  sysfs: fix use after free in case of concurrent read/write and readdir
  rtmutex-tester: fix mode of sysfs files
  Documentation: Add ABI entry for crash_notes and crash_notes_size
  sysfs: Add crash_notes_size to export percpu note size
  driver core: platform_device.h: fix checkpatch errors and warnings
  driver core: platform.c: fix checkpatch errors and warnings
  driver core: warn that platform_driver_probe can not use deferred probing
  sysfs: use atomic_inc_unless_negative in sysfs_get_active
  base: core: WARN() about bogus permissions on device attributes
  device: separate all subsys mutexes
