Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6: (61 commits) Dynamic debug: fix pr_fmt() build error Dynamic debug: allow simple quoting of words dynamic debug: update docs dynamic debug: combine dprintk and dynamic printk sysfs: fix some bin_vm_ops errors kobject: don't block for each kobject_uevent sysfs: only allow one scheduled removal callback per kobj Driver core: Fix device_move() vs. dpm list ordering, v2 Driver core: some cleanup on drivers/base/sys.c Driver core: implement uevent suppress in kobject vcs: hook sysfs devices into object lifetime instead of "binding" driver core: fix passing platform_data driver core: move platform_data into platform_device sysfs: don't block indefinitely for unmapped files. driver core: move knode_bus into private structure driver core: move knode_driver into private structure driver core: move klist_children into private structure driver core: create a private portion of struct device driver core: remove polling for driver_probe_done(v5) sysfs: reference sysfs_dirent from sysfs inodes ... Fixed conflicts in drivers/sh/maple/maple.c manually
