Merge tag 'driver-core-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core / sysfs patches from Greg KH: "Here's the big driver core / sysfs update for 3.13-rc1. There's lots of dev_groups updates for different subsystems, as they all get slowly migrated over to the safe versions of the attribute groups (removing userspace races with the creation of the sysfs files.) Also in here are some kobject updates, devres expansions, and the first round of Tejun's sysfs reworking to enable it to be used by other subsystems as a backend for an in-kernel filesystem. All of these have been in linux-next for a while with no reported issues" * tag 'driver-core-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (83 commits) sysfs: rename sysfs_assoc_lock and explain what it's about sysfs: use generic_file_llseek() for sysfs_file_operations sysfs: return correct error code on unimplemented mmap() mdio_bus: convert bus code to use dev_groups device: Make dev_WARN/dev_WARN_ONCE print device as well as driver name sysfs: separate out dup filename warning into a separate function sysfs: move sysfs_hash_and_remove() to fs/sysfs/dir.c sysfs: remove unused sysfs_get_dentry() prototype sysfs: honor bin_attr.attr.ignore_lockdep sysfs: merge sysfs_elem_bin_attr into sysfs_elem_attr devres: restore zeroing behavior of devres_alloc() sysfs: fix sysfs_write_file for bin file input: gameport: convert bus code to use dev_groups input: serio: remove bus usage of dev_attrs input: serio: use DEVICE_ATTR_RO() i2o: convert bus code to use dev_groups memstick: convert bus code to use dev_groups tifm: convert bus code to use dev_groups virtio: convert bus code to use dev_groups ipack: convert bus code to use dev_groups ...
