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: (36 commits) Driver core: show drivers in /sys/module/ Documentation/driver-model/platform.txt update/rewrite Driver core: platform_driver_probe(), can save codespace driver core: Use klist_remove() in device_move() driver core: Introduce device_move(): move a device to a new parent. Driver core: make drivers/base/core.c:setup_parent() static driver core: Introduce device_find_child(). sysfs: sysfs_write_file() writes zero terminated data cpu topology: consider sysfs_create_group return value Driver core: Call platform_notify_remove later ACPI: Change ACPI to use dev_archdata instead of firmware_data Driver core: add dev_archdata to struct device Driver core: convert sound core to use struct device Driver core: change mem class_devices to be real devices Driver core: convert fb code to use struct device Driver core: convert firmware code to use struct device Driver core: convert mmc code to use struct device Driver core: convert ppdev code to use struct device Driver core: convert PPP code to use struct device Driver core: convert cpuid code to use struct device ...
