USB: Fix up full-speed bInterval values in high-speed interrupt descriptor

Many device manufacturers are using full-speed bInterval values in high-speed
interrupt endpoint descriptors. If the bInterval value is greater than 16,
assume the device uses full-speed descriptors and fix the value accordingly.

them the way this one does - remove wrong call
- The tty buffer code isn't designed to be abused from IRQ handlers and

The driver now has some style, but not a lot - it goes insane if you have
two dongles for example as it continues to use global variables for per
dongle state. That bit isn't my problem.

This removes the ugly code that was copied from the keyspan driver and
allocates the in urbs in a much shorter code path that can be understood
easier.

Also turned off the interrupt urb when no port was open as it's not nice
to keep the bus busy for no good reason at all (this should be a power

usb_serial_get_by_index() gets a reference on the serial port under

Since the port has to be resumed anyway, we might as well reuse the
existing code.

usb_reset_suspended_device() is eliminated.

usb_root_hub_lost_power() is moved down next to the
hub_reset_resume() routine, to which it is logically
related.

finish_port_resume() does a port reset() if the device's
reset_resume flag is set.

usb_port_resume() doesn't check whether the port is initially
enabled if this is a USB-Persist sort of resume.

It is called when a device needs to be reset as part of a resume
procedure (whether because of a device quirk or because of the
USB-Persist facility), thereby taking over a role formerly assigned to
the post_reset method.  As a consequence, post_reset no longer needs
an argument indicating whether it is being called as part of a
reset-resume.  This separation of functions makes the code clearer.

In addition, the pre_reset and post_reset method return types are
changed; they now must return an error code.  The return value is
unused at present, but at some later time we may unbind drivers and
re-probe if they encounter an error during reset handling.

The existing pre_reset and post_reset methods in the usbhid,
usb-storage, and hub drivers are updated to match the new
requirements.  For usbhid the post_reset routine is also used for
reset_resume (duplicate method pointers); for the other drivers a new
reset_resume routine is added.  The change to hub.c looks bigger than
it really is, because mark_children_for_reset_resume() gets moved down
next to the new hub_reset_resume() routine.

A minor change to usb-storage makes the usb_stor_report_bus_reset()
routine acquire the host lock instead of requiring the caller to hold
it already.

USB: prevent char device open/deregister race

This patch (as908) adds central protection in usbcore for the
prototypical race between opening and unregistering a char device.
The spinlock used to protect the minor-numbers array is replaced with
an rwsem, which can remain locked across a call to a driver's open()
method.  This guarantees that open() and deregister() will be mutually
exclusive.

The private locks currently used in several individual drivers for
this purpose are no longer necessary, and the patch removes them.  The
following USB drivers are affected: usblcd, idmouse, auerswald,
legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and
usb-skeleton.

As a side effect of this change, usb_deregister_dev() must not be
called while holding a lock that is acquired by open().  Unfortunately
a number of drivers do this, but luckily the solution is simple: call
usb_deregister_dev() before acquiring the lock.

In addition to these changes (and their consequent code
simplifications), the patch fixes a use-after-free bug in adutux and a
race between open() and release() in iowarrior.

USB: don't unsuspend for a new connection

This patch (as889) prevents the hub driver from trying to resume a
port when there is a new connection.  For one thing, the resume is not
needed -- the upcoming port reset will clear the suspend feature
automatically.  For another, on some systems the resume fails and
causes problems.
