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: handle user namespaces properly with the uid/gid devtmpfs change 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
