this patch implements autosuspend for the usblcd driver. It uses

husb2dev was the internal name of the USB Device Controller on
AT32AP7000. Rename it to "atmel_usba", which is closer to the official
name used in documentation and marketing material.

USB: Add URB_FREE_BUFFER flag for freeing the transfer buffer

In some cases it is not needed that the driver keeps track of the
transfer buffer of an URB. It can be simply freed along with the
URB itself when the reference count goes down to zero. The new
flag URB_FREE_BUFFER enables this behavior.

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.

- Drivers don't call ldisc termios methods. They certainly don't call
them the way this one does - remove wrong call
- The tty buffer code isn't designed to be abused from IRQ handlers and
the new buffering removes the need for the uglies involved - fix them
- Style
- Remove incorrect baud and change handling for termios changes

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.

Use the baud rate stuff from the kernel don't parse CBAUD directly
Remove pointless and wrong 'no change' check

Could do with some good testing as well but again better than adding &&
BROKEN

(The use of BELKIN_SA_BAUD() might seem a bit odd but x/a = b and x/b =
a (rounded for integers)).

o	Don't parse the cflag for baud rates, its not valid to do so
	any more and this driver got it wrong anyway
o	Don't do clever termios change checks in drivers and get them
	wrong (arguably we should do some smart ones in the tty core but
	stty to change nothing is *not* a common or critical path

I don't have the hardware so if you can test this carefully please do. I
thought fixing it up this far was better than marking it and other bits of
USB serial && BROKEN

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
savings.)

All in all, this saved over 40 lines of code and cleaned things up
better.

You can't rely on the fact that the status really is correct like it was.

Also simplified the write path and now we allocate the urb and data on
the fly, instead of trying to do that really odd timeout check which I
am guessing doesn't really work properly.  This should speed up the
device by keeping the hardware queue full easier.

As a benefit, this reduces the size of the driver.
