A few patches ago, I removed the reset_resume callback, changing it to
resume instead.  Now that the usb-serial core supports reset_resume, put
this driver callback back as well, so it should work identically to how
it was originally.

Now if this function really is doing what it should be doing, well,
that's a different story, but we are at least doing the identical thing
that we were before...

The callback is now hooked up for any USB to serial driver that wants
it.  We only register the callback if any of the usb-serial structures
want it, this keeps the USB core happy.

Thanks to Alan Stern for the ideas on how to do this.

Keep the usb-serial support for dynamic IDs in sync with the usb
support.  This enables readout of dynamic device IDs for
usb-serial drivers.  Common code is exported from the usb core
system and reused by the usb-serial bus driver.

With a previous patch, the usb_driver suspend/resume callbacks got
overridden and were never called if a usb_serial driver defined them.
This patch fixes the opticon driver to move the suspend/resume callbacks
into the usb_serial_driver structure where they will be properly called.

It then removes the unused usb_driver structure.

This reworks the usb_serial_register_drivers() and
usb_serial_deregister_drivers() to not need a pointer to a struct
usb_driver anymore.  The usb_driver structure is now created dynamically
and registered and unregistered as needed.

This saves lines of code in each usb-serial driver.  All in-kernel users
of these functions were also fixed up at this time.  The pl2303 driver
was tested that everything worked properly.

Thanks for the idea to do this from Alan Stern.

I can't remember why I wrote it like this many many years ago, but it's
not needed at all, let's rely on the usb-serial core for this function,
especially as it is being overridden by it anyway.

This lets us make usb_serial_probe() a static function, which it should
be.

This patch (as1551) cleans up the PM-related entries in the usb_driver
structures of the various USB serial driver modules.  Those entries
are now filled in by the usb-serial core during driver registration,
so they don't need to be initialized explicitly in the source code.

The same is true of the one remaining no_dynamic_id entry.

reset_resume remains a small problem, because the serial core doesn't
support it.  The patch ignores these entries.

This patch (as1550) fixes a bug in the usb-serial core that affects
the ftdi_sio driver and most likely others as well.  The core
implements suspend and resume routines, but it doesn't store pointers
to those routines in the usb_driver structures that it registers,
even though it does set those drivers' supports_autosuspend flag.  The
end result is that when one of these devices is autosuspended, we try
to call through a NULL pointer.

The patch fixes the problem by setting the suspend and resume method
pointers to the appropriate routines in the USB serial core, along
with the supports_autosuspend field, in each driver as it is
registered.

This should be back-ported to all the stable kernels that have the new
usb_serial_register_drivers() interface.
