* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6: (27 commits)
  Driver core: fix race in dev_driver_string
  Driver Core: Early platform driver buffer
  sysfs: sysfs_setattr remove unnecessary permission check.
  sysfs: Factor out sysfs_rename from sysfs_rename_dir and sysfs_move_dir
  sysfs: Propagate renames to the vfs on demand
  sysfs: Gut sysfs_addrm_start and sysfs_addrm_finish
  sysfs: In sysfs_chmod_file lazily propagate the mode change.
  sysfs: Implement sysfs_getattr & sysfs_permission
  sysfs: Nicely indent sysfs_symlink_inode_operations
  sysfs: Update s_iattr on link and unlink.
  sysfs: Fix locking and factor out sysfs_sd_setattr
  sysfs: Simplify iattr time assignments
  sysfs: Simplify sysfs_chmod_file semantics
  sysfs: Use dentry_ops instead of directly playing with the dcache
  sysfs: Rename sysfs_d_iput to sysfs_dentry_iput
  sysfs: Update sysfs_setxattr so it updates secdata under the sysfs_mutex
  debugfs: fix create mutex racy fops and private data
  Driver core: Don't remove kobjects in device_shutdown.
  firmware_class: make request_firmware_nowait more useful
  Driver-Core: devtmpfs - set root directory mode to 0755
