Alan Stern 29618e9fb5 usb-serial: use new registration API in [t-z]* drivers
This patch (as1529) modifies the following usb-serial drivers to
utilize the new usb_serial_{de}register_drivers() routines:

	ti_usb_3410_5052, usb_debug, visor, vivopay-serial,
	whiteheat, and zio.

Rusty Russell 90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Alan Cox 60b33c133c tiocmget: kill off the passing of the struct file
We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

Alan Stern f9c99bb8b3 USB: usb-serial: replace shutdown with disconnect, release
This patch (as1254) splits up the shutdown method of usb_serial_driver
into a disconnect and a release method.

The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed.  The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.

Alan Cox 95da310e66 usb_serial: API all change
USB serial likes to use port->tty back pointers for the real work it does and
to do so without any actual locking. Unfortunately when you consider hangup
events, hangup/parallel reopen or even worse hangup followed by parallel close
events the tty->port and port->tty pointers are not guaranteed to be the same
as port->tty is the active tty while tty->port is the port the tty may or
may not still be attached to.

So rework the entire API to pass the tty struct. For console cases we need
to pass both for now. This shows up multiple drivers that immediately crash
with USB console some of which have been fixed in the process.

Longer term we need a proper tty as console abstraction

Greg Kroah-Hartman 0ba4034e20 USB: serial: remove unneeded number endpoints settings
The usb-serial core no longer checks these fields so remove them from
all of the individual drivers.  They will be removed from the usb-serial
core in a patch later in the series.

Matthew Wilcox d3135846f6 drivers: Remove unnecessary inclusions of asm/semaphore.h
None of these files use any of the functionality promised by
asm/semaphore.h.  It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

Robert Spanton 1bfd6693cd USB: serial: ti_usb_3410_5052: Correct TUSB3410 endpoint requirements.
The changes introduced in commit
063a2da8f0 changed the semantics of the
num_interrupt_in, num_interrupt_out, num_bulk_in and num_bulk_out
entries of the usb_serial_driver struct to be the number of endpoints
the device has when probed.

This patch changes the ti_1port_device usb_serial_driver struct to
reflect this change.  The single port devices only have 1
bulk_out endpoint in their initial configuration, and so this patch
changes the number of other types to NUM_DONT_CARE.

The same change probably needs doing to the ti_2port_device struct,
but I don't have a two port device at hand.

Oliver Neukum 0915f490d8 USB: last abuses of intfdata in close for usb-serial drivers
these drivers abused intfdata in close() as flags for binding.
That races with reprobing of those devices. This patch fixes that by using
the flag and the locks introduced with the patch against mos7720.
