* driver core: fix a lot of printk usages of bus_idGreg Kroah-Hartman2008-07-2114-45/+32
| | | | | | | | | | We have the dev_printk() variants for this kind of thing, use them instead of directly trying to access the bus_id field of struct device. This is done in order to remove bus_id entirely. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* driver core: remove DEVICE_ID_SIZE defineGreg Kroah-Hartman2008-07-212-3/+2
| | | | | | | | | There is no such thing as a "device id size" in the driver core, so remove the define and fix up any users of this odd define in the rest of the kernel. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* driver core: remove KOBJ_NAME_LEN defineKay Sievers2008-07-2116-26/+26
| | | | | | | | | Kobjects do not have a limit in name size since a while, so stop pretending that they do. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* class: change internal semaphore to a mutexDave Young2008-07-213-17/+19
| | | | | | | | | | | | | | | | Now that the lockdep infrastructure in the class core is in place, we should be able to properly change the internal class semaphore to be a mutex. David wrote the original patch, and Greg fixed it up to apply properly due to all of the recent changes in this area.

* class: add lockdep infrastructureMatthew Wilcox2008-07-212-7/+29
| | | | | | | | | | | | | | | | | | This adds the infrastructure to properly handle lockdep issues when the internal class semaphore is changed to a mutex. Matthew wrote the original patch, and Greg fixed it up to work properly with the class_create() function.

* class: rename "sem" to "class_sem" in internal class structureGreg Kroah-Hartman2008-07-213-17/+17
| | | | | | | | | | | This renames the struct class "sem" field to be "class_sem" to make things easier when struct bus_type and struct class merge in the future. It also makes grepping for fields easier as well. Based on an idea from Kay. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* class: move driver core specific parts to a private structureGreg Kroah-Hartman2008-07-214-71/+107
| | | | | | | | | | | This moves the portions of struct class that are dynamic (kobject and lock and lists) out of the main structure and into a dynamic, private, structure. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* bluetooth: remove improper bluetooth class symlinks.Greg Kroah-Hartman2008-07-211-7/+0
| | | | | | | | | | | | Don't create symlinks in a class to a device that is not owned by the class. If the bluetooth subsystem really wants to point to all of the devices it controls, it needs to create real devices, not fake symlinks.

* infiniband: make cm_device use a struct device and not a kobject.Greg Kroah-Hartman2008-07-211-20/+9
| | | | | | | | | | | | | | | | This object really should be a struct device, or at least contain a pointer to a struct device, as it is trying to create a separate device tree outside of the main device tree. This patch fixes this problem. It is needed for the class core rework that is being done in the driver core.

* infiniband: rename "device" to "ib_device" in cm_deviceGreg Kroah-Hartman2008-07-211-23/+24
| | | | | | | | | | | | | | This pointer really is a struct ib_device, not a struct device, so name it properly to help prevent confusion. This makes the followon patch in this series much smaller and easier to understand as well.

* block: move header for /proc/partitions to seq_startGreg Kroah-Hartman2008-07-211-3/+4
| | | | | | | | | The seq_start call is the better place for the header for the file, that way we don't have to be mucking in the class structure to try to figure out if this is the first partition or not. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | These functions are only needed if CONFIG_PROC_FS is enabled, so save the space when it is not.

| | | | | | | | | | | | | | | This mirrors the functionality that driver_find_device has as well. We add a start variable, and all callers of the function are fixed up at the same time.

| | | | | | | | | | | | | Switch over to use the shiny new device_create_drvdata() call instead of the original device_create() calls, so this continues to work after device_create() is removed. Note that this driver never had the race which motivated removing the original call; it locked correctly.
