Merge master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6: (75 commits) PM: merge device power-management source files sysfs: add copyrights kobject: update the copyrights kset: add some kerneldoc to help describe what these strange things are Driver core: rename ktype_edd and ktype_efivar Driver core: rename ktype_driver Driver core: rename ktype_device Driver core: rename ktype_class driver core: remove subsystem_init() sysfs: move sysfs file poll implementation to sysfs_open_dirent sysfs: implement sysfs_open_dirent sysfs: move sysfs_dirent->s_children into sysfs_dirent->s_dir sysfs: make sysfs_root a regular directory dirent sysfs: open code sysfs_attach_dentry() sysfs: make s_elem an anonymous union sysfs: make bin attr open get active reference of parent too sysfs: kill unnecessary NULL pointer check in sysfs_release() sysfs: kill unnecessary sysfs_get() in open paths sysfs: reposition sysfs_dirent->s_mode. sysfs: kill sysfs_update_file() ...
