Greg Kroah-Hartman b87ba0a33a [PATCH] add EXPORT_SYMBOL_GPL_FUTURE() to USB subsystem
The USB core symbols will be converted to GPL-only in a few years.  Mark
this as such and update the documentation explaining why, and provide a
pointer for developers to receive help if they need it.

Greg KH 410c05427a [PATCH] USB: Fix GPL markings on usb core functions.
I thought we had fixed up all non-gpl USB drivers, and was wrong to do
this.

Alan Stern 9ad3d6ccf5 [PATCH] USB: Remove USB private semaphore
This patch (as605) removes the private udev->serialize semaphore,
relying instead on the locking provided by the embedded struct device's
semaphore.  The changes are confined to the core, except that the
usb_trylock_device routine now uses the return convention of
down_trylock rather than down_read_trylock (they return opposite values
for no good reason).

A couple of other associated changes are included as well:

	Now that we aren't concerned about HCDs that avoid using the
	hcd glue layer, usb_disconnect no longer needs to acquire the
	usb_bus_lock -- that can be done by usb_remove_hcd where it
	belongs.

	Devices aren't locked over the same scope of code in
	usb_new_device and hub_port_connect_change as they used to be.
	This shouldn't cause any trouble.

Along with the preceding driver core patch, this needs a lot of testing.

Greg Kroah-Hartman 2143acc6dc [PATCH] USB: make registering a usb driver automatically set the module owner
This fixes the driver that forgot to set the module owner up.  Now we
can remove the unneeded pointer from the usb driver structure.  The idea
for how to do this was from Al Viro, who did this for the PCI drivers.

Greg Kroah-Hartman ba9dc657af [PATCH] USB: allow usb drivers to disable dynamic ids
This lets drivers, like the usb-serial ones, disable the ability to add
ids from sysfs.

The usb-serial drivers are "odd" in that they are really usb-serial bus
drivers, not usb bus drivers, so the dynamic id logic will have to go
into the usb-serial bus core for those drivers to get that ability.

Greg Kroah-Hartman 733260ff9c [PATCH] USB: add dynamic id functionality to USB core
Echo the usb vendor and product id to the "new_id" file in the driver's
sysfs directory, and then that driver will be able to bind to a device
with those ids if it is present.

Example:
	echo 0557 2008 > /sys/bus/usb/drivers/foo_driver/new_id
adds the hex values 0557 and 2008 to the device id table for the foo_driver.

Note, usb-serial drivers do not currently work with this capability yet.
usb-storage also might have some oddities.

Greg Kroah-Hartman ddae41be61 [PATCH] USB: reorg some functions out of the main usb.c file
This will make the dynamic-id stuff easier to do, as it will be
self-contained.

No logic was changed at all.
