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: (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 ...
