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:
UIO: fix specific device driver missing statement for depmod
Driver core: remove pr_fmt() from dynamic_dev_dbg() printk
driver core: prevent device_for_each_child from oopsing
dynamic debug: resurrect old pr_debug() semantics as pr_devel()
Driver Core: early platform driver
proc: mounts_poll() make consistent to mdstat_poll
sysfs: sysfs poll keep the poll rule of regular file.
driver core: allow non-root users to listen to uevents
driver core: fix driver_match_device
sysfs: don't use global workqueue in sysfs_schedule_callback()
